high Nessus Plugin ID 93943

Language:

Synopsis

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

Description

The implementation of bspatch is susceptible to integer overflows with carefully crafted input, potentially allowing an attacker who can control the patch file to write at arbitrary locations in the heap.
This issue was partially addressed in FreeBSD-SA-16:25.bspatch, but some possible integer overflows remained. Impact : An attacker who can control the patch file can cause a crash or run arbitrary code under the credentials of the user who runs bspatch, in many cases, root.

Solution

Update the affected packages.
