libgc vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
Summary:
Applications using libgc could be made to crash or run arbitrary
programs as your login.
Software Description:
- libgc: Boehm-Demers-Weiser garbage collecting storage allocator library
Details:
It was discovered that multiple integer overflows existed in the
malloc and calloc implementations in the Boehm-Demers-Weiser garbage
collecting memory allocator (libgc). These could allow an attacker
to cause a denial of service or possibly execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
libgc1c2 1:7.1-8ubuntu0.12.04.1
Ubuntu 11.10:
libgc1c2 1:7.1-8ubuntu0.11.10.1
Ubuntu 11.04:

Ubuntu 10.04 LTS:
libgc1c2 1:6.8-1.2ubuntu1.1
Ubuntu 8.04 LTS:
libgc1c2 1:6.8-1.1ubuntu0.1
In general, a standard system update will make all the necessary changes.
