Debian DLA-2010-1 : bsdiff security update

high Nessus Plugin ID 131329

Synopsis

The remote Debian host is missing a security update.

Description

An issue in bsdiff, a tool to generate/apply a patch between two binary files, has been found.

Using a crafted patch file an integer signedness error in bspatch could be used for a heap based buffer overflow and possibly execution of arbitrary code.

For Debian 8 'Jessie', this problem has been fixed in version 4.3-15+deb8u1.

We recommend that you upgrade your bsdiff packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected bsdiff package.
