According to the versions of the openssl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A NULL pointer dereference flaw was found in OpenSSL's     X.509 certificate handling implementation. A specially     crafted X.509 certificate could cause an application     using OpenSSL to crash if the application attempted to     convert the certificate to a certificate     request.(CVE-2015-0288)

  - Off-by-one error in the DTLS implementation in OpenSSL     0.9.8 before 0.9.8f allows remote attackers to execute     arbitrary code via unspecified vectors.(CVE-2007-4995)

  - An integer underflow flaw, leading to a buffer     overflow, was found in the way OpenSSL decoded     malformed Base64-encoded inputs. An attacker able to     make an application using OpenSSL decode a specially     crafted Base64-encoded input (such as a PEM file) could     use this flaw to cause the application to crash. Note:
    this flaw is not exploitable via the TLS/SSL protocol     because the data being transferred is not     Base64-encoded.(CVE-2015-0292)

  - OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when     SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled,     does not properly prevent modification of the     ciphersuite in the session cache, which allows remote     attackers to force the downgrade to an unintended     cipher via vectors involving sniffing network traffic     to discover a session identifier.(CVE-2010-4180)

  - OpenSSL before 0.9.8m does not check for a NULL return     value from bn_wexpand function calls in (1)     crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3)     crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which     has unspecified impact and context-dependent attack     vectors.(CVE-2009-3245)

  - The Cryptographic Message Syntax (CMS) implementation     in crypto/cms/cms_asn1.c in OpenSSL before 0.9.8o and     1.x before 1.0.0a does not properly handle structures     that contain OriginatorInfo, which allows     context-dependent attackers to modify invalid memory     locations or conduct double-free attacks, and possibly     execute arbitrary code, via unspecified     vectors.(CVE-2010-0742)

  - Race condition in the ssl3_read_bytes function in     s3_pkt.c in OpenSSL through 1.0.1g, when     SSL_MODE_RELEASE_BUFFERS is enabled, allows remote     attackers to inject data across sessions or cause a     denial of service (use-after-free and parsing error)     via an SSL connection in a multithreaded     environment.(CVE-2010-5298)

  - The BN_from_montgomery function in crypto/bn/bn_mont.c     in OpenSSL 0.9.8e and earlier does not properly perform     Montgomery multiplication, which might allow local     users to conduct a side-channel attack and retrieve RSA     private keys.(CVE-2007-3108)

  - A memory leak flaw was found in the way an OpenSSL     handled failed session ticket integrity checks. A     remote attacker could exhaust all available memory of     an SSL/TLS or DTLS server by sending a large number of     invalid session tickets to that server.(CVE-2014-3567)

  - It was discovered that OpenSSL would perform an ECDH     key exchange with a non-ephemeral key even when the     ephemeral ECDH cipher suite was selected. A malicious     server could make a TLS/SSL client using OpenSSL use a     weaker key exchange method than the one requested by     the user.(CVE-2014-3572)

  - A denial of service flaw was found in the way OpenSSL     handled certain DTLS ServerHello requests. A specially     crafted DTLS handshake packet could cause a DTLS client     using OpenSSL to crash.(CVE-2014-0221)

  - A NULL pointer dereference was found in the way OpenSSL     handled certain PKCS#7 inputs. An attacker able to make     an application using OpenSSL verify, decrypt, or parse     a specially crafted PKCS#7 input could cause that     application to crash. TLS/SSL clients and servers using     OpenSSL were not affected by this flaw.(CVE-2015-1790)

  - The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0     and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and     other products, do not properly consider timing     side-channel attacks on a MAC check requirement during     the processing of malformed CBC padding, which allows     remote attackers to conduct distinguishing attacks and     plaintext-recovery attacks via statistical analysis of     timing data for crafted packets, aka the 'Lucky     Thirteen' issue.(CVE-2013-0169)

  - OpenSSL 0.9.8i and earlier does not properly check the     return value from the EVP_VerifyFinal function, which     allows remote attackers to bypass validation of the     certificate chain via a malformed SSL/TLS signature for     DSA and ECDSA keys.(CVE-2008-5077)

  - The TLS protocol, and the SSL protocol 3.0 and possibly     earlier, as used in Microsoft Internet Information     Services (IIS) 7.0, mod_ssl in the Apache HTTP Server     2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5     and earlier, Mozilla Network Security Services (NSS)     3.12.4 and earlier, multiple Cisco products, and other     products, does not properly associate renegotiation     handshakes with an existing connection, which allows     man-in-the-middle attackers to insert data into HTTPS     sessions, and possibly other types of sessions     protected by TLS or SSL, by sending an unauthenticated     request that is processed retroactively by a server in     a post-renegotiation context, related to a 'plaintext     injection' attack, aka the 'Project Mogul'     issue.(CVE-2009-3555)

  - Multiple memory leaks in the     dtls1_process_out_of_seq_message function in     ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8     versions allow remote attackers to cause a denial of     service (memory consumption) via DTLS records that (1)     are duplicates or (2) have sequence numbers much     greater than current sequence numbers, aka 'DTLS     fragment handling memory leak.'(CVE-2009-1378)

  - The dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows     remote attackers to cause a denial of service (NULL     pointer dereference and daemon crash) via an     out-of-sequence DTLS handshake message, related to a     'fragment bug.'(CVE-2009-1387)

  - There is a carry propagating bug in the x86_64     Montgomery squaring procedure in OpenSSL before 1.0.2m     and 1.1.0 before 1.1.0g. No EC algorithms are affected.
    Analysis suggests that attacks against RSA and DSA as a     result of this defect would be very difficult to     perform and are not believed likely. Attacks against DH     are considered just feasible (although very difficult)     because most of the work necessary to deduce     information about a private key may be performed     offline. The amount of resources required for such an     attack would be very significant and likely only     accessible to a limited number of attackers. An     attacker would additionally need online access to an     unpatched system using the target private key in a     scenario with persistent DH parameters and a private     key that is shared between multiple clients. This only     affects processors that support the BMI1, BMI2 and ADX     extensions like Intel Broadwell (5th generation) and     later or AMD Ryzen.(CVE-2017-3736)

  - A flaw was discovered in the way OpenSSL handled DTLS     packets. A remote attacker could use this flaw to cause     a DTLS server or client using OpenSSL to crash or use     excessive amounts of memory.(CVE-2014-3505)

  - The dtls1_reassemble_fragment function in d1_both.c in     OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1     before 1.0.1h does not properly validate fragment     lengths in DTLS ClientHello messages, which allows     remote attackers to execute arbitrary code or cause a     denial of service (buffer overflow and application     crash) via a long non-initial fragment.(CVE-2014-0195)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that OpenSSL did not correctly perform Montgomery multiplications. Local attackers might be able to reconstruct RSA private keys by examining another user's OpenSSL processes.
(CVE-2007-3108)

Moritz Jodeit discovered that OpenSSL's SSL_get_shared_ciphers function did not correctly check the size of the buffer it was writing to. A remote attacker could exploit this to write one NULL byte past the end of an application's cipher list buffer, possibly leading to arbitrary code execution or a denial of service. (CVE-2007-5135).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A flaw was found in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer by a single byte (CVE-2007-5135). Few applications make use of this vulnerable function and generally it is used only when applications are compiled for debugging.

A number of possible side-channel attacks were discovered affecting OpenSSL. A local attacker could possibly obtain RSA private keys being used on a system. In practice these attacks would be difficult to perform outside of a lab environment. This update contains backported patches to mitigate these issues. (CVE-2007-3108)

As well, these updated packages fix the following bugs :

  - multithreaded applications could cause a segmentation     fault or deadlock when calling the random number     generator initialization (RAND_poll) in the OpenSSL     library, for a large number of threads simultaneously.

  - in certain circumstances, if an application using the     OpenSSL library reused the SSL session cache for     multiple purposes (with various parameters of the SSL     protocol), the session parameters could be mismatched.

  - a segmentation fault could occur when a corrupted pkcs12     file was being loaded using the 'openssl pkcs12 -in     [pkcs12-file]' command, where [pkcs12-file] is the     pkcs12 file.

Updated OpenSSL packages that correct a security issue and various bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, and is also a full-strength general-purpose cryptography library.

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has openssl packages installed that are affected by multiple vulnerabilities:

  - In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances     where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection     were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other     places in the script where the file names of certificates being hashed were possibly passed to a command     executed through the shell. This script is distributed by some operating systems in a manner where it is     automatically executed. On such operating systems, an attacker could execute arbitrary commands with the     privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the     OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in     OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze). (CVE-2022-2068)

  - The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat     Extension packets, which allows remote attackers to obtain sensitive information from process memory via     crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to     d1_both.c and t1_lib.c, aka the Heartbleed bug. (CVE-2014-0160)

  - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service     (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled     error condition. (CVE-2006-2937)

  - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial     of service (CPU consumption) via parasitic public keys with large (1) public exponent or (2) public     modulus values in X.509 certificates that require extra time to process when using RSA signature     verification. (CVE-2006-2940)

  - Buffer overflow in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before     0.9.8d, and earlier versions has unspecified impact and remote attack vectors involving a long list of     ciphers. (CVE-2006-3738)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated OpenSSL packages that correct several security issues are now available for Red Hat Enterprise 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

OpenSSL is a toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. Datagram TLS (DTLS) is a protocol based on TLS that is capable of securing datagram transport (UDP for instance).

The OpenSSL security team discovered a flaw in DTLS support. An attacker could create a malicious client or server that could trigger a heap overflow. This is possibly exploitable to run arbitrary code, but it has not been verified (CVE-2007-4995). Note that this flaw only affects applications making use of DTLS. Red Hat does not ship any DTLS client or server applications in Red Hat Enterprise Linux.
