FreeBSD : Mozilla -- XPath parsing undefined behavior (a2d5bd7b-2e85-11f0-a989-b42e991fc52e)

medium Nessus Plugin ID 235697

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the a2d5bd7b-2e85-11f0-a989-b42e991fc52e advisory.

[email protected] reports:
A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to missing null checks during attribute access. This could lead to out-of-bounds read access and potentially, memory corruption.

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

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

Solution

Update the affected packages.
