Debian DLA-721-1 : libgc security update

critical Nessus Plugin ID 95357

Language:

Synopsis

The remote Debian host is missing a security update.

Description

libgc is vulnerable to integer overflows in multiple places. In some cases, when asked to allocate a huge quantity of memory, instead of failing the request, it will return a pointer to a small amount of memory possibly tricking the application into a buffer overwrite.

For Debian 7 'Wheezy', these problems have been fixed in version 1:7.1-9.1+deb7u1.

We recommend that you upgrade your libgc 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 libgc-dev, and libgc1c2 packages.
