Debian DLA-2088-1 : libsolv security update

high Nessus Plugin ID 133364

Language:

Synopsis

The remote Debian host is missing a security update.

Description

repodata_schema2id in repodata.c in libsolv, a dependency solver library, had a heap-based buffer over-read via a last schema whose length could be less than the length of the input schema.

For Debian 8 'Jessie', this problem has been fixed in version 0.6.5-1+deb8u1.

We recommend that you upgrade your libsolv 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 packages.
