Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : Samba vulnerabilities (USN-7582-1)

critical Nessus Plugin ID 240197

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7582-1 advisory.

 Evgeny Legerov discovered that Samba incorrectly handled buffers in certain GSSAPI routines of Heimdal. A remote attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service.
 (CVE-2022-3437)

 Greg Hudson discovered that Samba incorrectly handled PAC parsing. On 32-bit systems, a remote attacker could use this issue to escalate privileges, or possibly execute arbitrary code. (CVE-2022-42898)

 Joseph Sutton discovered that Samba could be forced to issue rc4-hmac encrypted Kerberos tickets. A remote attacker could possibly use this issue to escalate privileges. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-45141)

 Florent Saudel discovered that Samba incorrectly handled certain Spotlight requests. A remote attacker could possibly use this issue to cause Samba to consume resources, leading to a denial of service.
 (CVE-2023-34966)

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

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