FreeBSD : libarchive -- Infinite loop in corrupt archives handling in libarchive (792bc222-c5d7-11db-9f82-000e0c2e438a)

medium Nessus Plugin ID 24720

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

If the end of an archive is reached while attempting to 'skip' past a region of an archive, libarchive will enter an infinite loop wherein it repeatedly attempts (and fails) to read further data. Impact : An attacker able to cause a system to extract (via 'tar -x' or another application which uses libarchive) or list the contents (via 'tar -t' or another libarchive-using application) of an archive provided by the attacker can cause libarchive to enter an infinite loop and use all available CPU time. Workaround : No workaround is available.

Solution

Update the affected package.
