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

high Nessus Plugin ID 162821

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5506-1 advisory.

 - Within the <code>lg_init()</code> function, if several allocations succeed but then one fails, an uninitialized pointer would have been freed despite never being allocated. This vulnerability affects Firefox < 102. (CVE-2022-34480)

 - After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2022-22747)

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.
