An update of the libcap package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0173 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2023-2602:
      A vulnerability was found in the pthread_create() function in libcap. This issue may allow a malicious     actor to use cause __real_pthread_create() to return an error, which can exhaust the process memory.

      CVE-2023-2603:
      A vulnerability was found in libcap. This issue occurs in the _libcap_strdup() function and can lead to     an integer overflow if the input string is close to 4GiB.

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.100173 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange     differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. (CVE-2023-5981)

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

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.216 advisory.

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems.

    (CVE-2023-2283)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
    (CVE-2023-2828)

  - Buffer Overflow vulnerability found in SQLite3 v.3.27.1 and before allows a local attacker to cause a     denial of service via a crafted script. (CVE-2020-24736)

    Package        : libcap2     Version        : 1:2.44-1+deb11u1     CVE IDs        : CVE-2023-2602 CVE-2023-2603 CVE-2025-1390     Debian Bugs    : 1036114 1098318

    It was discovered that there were three issues in libcap2, a library     for managing kernel capabilities; that is, partitioning the     powerful single root privilege into a set of distinct privileges,     typically used to limit any damage if a process running as the root     user is exploited. The three issues are as follows:

    * CVE-2023-2602: A vulnerability was found in the pthread_create()       function. This issue could have allowed a malicious actor in order       to exhaust the system's memory.

    * CVE-2023-2603: An issue was found in the _libcap_strdup function       which could have led to an integer overflow if the input string was       close to 4GiB.

    * CVE-2025-1390: The pam_cap.so PAM module supports group names       starting with @ but during parsing, configurations not starting       with @ were incorrectly recognised as group names. This       user-group confusion may have resulted in unintended users being       granted an inherited capability set, potentially leading to       security risks. Attackers could have exploited this vulnerability       to achieve local privilege escalation on systems where       capability.conf was used to configure user inherited privileges by       constructing specific usernames.

    For Debian 11 bullseye, these problems have been fixed in version     1:2.44-1+deb11u1.

    We recommend that you upgrade your libcap2 packages.
