Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6154-1 advisory.

 It was discovered that Vim was using uninitialized memory when fuzzy matching, which could lead to invalid memory access. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, Ubuntu 22.10 and Ubuntu 23.04. (CVE-2023-2426)

 It was discovered that Vim was not properly performing bounds checks when processing register contents, which could lead to a NULL pointer dereference. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2023-2609)

 It was discovered that Vim was not properly limiting the length of substitution expression strings, which could lead to excessive memory consumption. An attacker could possibly use this issue to cause a denial of service. (CVE-2023-2610)

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.
