Package : libgc
Version : 1:7.1-9.1+deb7u1
CVE ID : CVE-2016-9427
Debian Bug : 844771

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.
