The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2019-4118:02 advisory.

    * openssh: User enumeration via malformed packets in authentication requests (CVE-2018-15473)

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2019-2143 advisory.

    - Fix for CVE-2018-15473 (#1619079)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

Dariusz Tytko, Michal Sajdak and Qualys Security discovered that OpenSSH, an implementation of the SSH protocol suite, was prone to a user enumeration vulnerability. This would allow a remote attacker to check whether a specific user account existed on the target server.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2019-0711 advisory.

This update for openssh fixes the following issues :

Security issues fixed :

CVE-2018-15919: Remotely observable behaviour in auth-gss2.c in OpenSSH could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. OpenSSH developers do not want to treat such a username enumeration (or 'oracle') as a vulnerability.
(bsc#1106163)

CVE-2017-15906: The process_open function in sftp-server.c in OpenSSH did not properly prevent write operations in readonly mode, which allowed attackers to create zero-length files. (bsc#1065000, bsc#1106726)

CVE-2016-10708: sshd allowed remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. (bsc#1076957)

CVE-2018-15473: OpenSSH was prone to a user existance oracle vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. (bsc#1105010)

CVE-2016-10012: Removed pre-auth compression support from the server to prevent possible cryptographic attacks. (bsc#1016370)

Bugs fixed: Fixed failing 'AuthorizedKeysCommand' within a 'Match User' block in sshd_config (bsc#1105180)

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

The version of AOS installed on the remote host is prior to 5.10.9. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.10.9 advisory.

  - Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow     can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels,     assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass     invalid utf-8 strings to functions like pango_itemize. (CVE-2019-1010238)

  - curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal     function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how     large temporary storage area to allocate from the heap. The length value is then subsequently used to     iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit     size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31     bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the     intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is     almost identical to CVE-2017-8816.) (CVE-2018-14618)

  - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can     send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed     later on, leading to DoS (segmentation fault). (CVE-2018-14598)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable     to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other     impact. (CVE-2018-14599)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a     variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading     to DoS or remote code execution. (CVE-2018-14600)

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