DLA-2966-1 libgc -- LTS security update

Date Reported:

30 Mar 2022

Affected Packages:

libgc

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2016-9427.

More information:

libgc, a conservative garbage collector, 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 9 stretch, this problem has been fixed in version 1:7.4.2-8+deb9u1.

We recommend that you upgrade your libgc packages.
