Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7314-1 advisory.

 It was discovered that Kerberos incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause Kerberos to consume memory,leading to a denial of service.
 (CVE-2024-26458, CVE-2024-26461)

 It was discovered that Kerberos incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause Kerberos to consume memory,leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-26462)

 It was discovered that the Kerberos kadmind daemon incorrectly handled log files when incremental propagation was enabled. An authenticated attacker could use this issue to cause kadmind to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-24528)

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.

Solution

Update the affected packages.
