Debian Security Advisory

DLA-721-1 libgc -- LTS security update

Date Reported:

25 Nov 2016

Affected Packages:

libgc

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 844771.
In Mitre's CVE dictionary: CVE-2016-9427.

More information:

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.
