Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : NSS vulnerabilities (USN-5506-1)

high Nessus Plugin ID 162821

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5506-1 advisory.

Tavis Ormandy discovered that NSS incorrectly handled an empty pkcs7 sequence. A remote attacker could possibly use this issue to cause NSS to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 21.10. (CVE-2022-22747)

Ronald Crane discovered that NSS incorrectly handled certain memory operations. A remote attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-34480)

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 libnss3, libnss3-dev and / or libnss3-tools packages.
