Debian: Security update for evince

Jon Larimer from IBM X-Force Advanced Research discovered multiple vulnerabilities in the DVI backend of the evince document viewer. Insuficient array bounds checks in the PK fonts parser could lead to function pointer overwrite, causing arbitrary code execution. Insuficient array bounds checks in the PK fonts parser could lead to function pointer overwrite, causing arbitrary code execution. Insuficient bounds checks in the AFM fonts parser when writing data to a memory buffer allocated on heap could lead to arbitrary memory overwrite and arbitrary code execution.

Insuficient check on an integer used as a size for memory allocation can lead to arbitrary write outside the allocated range and cause arbitrary code execution. Updated packages are available from security.debian.org.

Debian Bug     : 609534

Jon Larimer from IBM X-Force Advanced Research discovered multiple
vulnerabilities in the DVI backend of the evince document viewer:

CVE-2010-2640

   Insuficient array bounds checks in the PK fonts parser could lead
   to function pointer overwrite, causing arbitrary code execution.

CVE-2010-2641

   Insuficient array bounds checks in the PK fonts parser could lead
   to function pointer overwrite, causing arbitrary code execution.

CVE-2010-2642

   Insuficient bounds checks in the AFM fonts parser when writing
   data to a memory buffer allocated on heap could lead to arbitrary
   memory overwrite and arbitrary code execution.

CVE-2010-2643

   Insuficient check on an integer used as a size for memory
   allocation can lead to arbitrary write outside the allocated range
   and cause arbitrary code execution.

For the oldstable distribution (lenny), this problem has been fixed in
version 2.22.2-4~lenny2.

For the stable distribution (squeeze), CVE-2010-2640, CVE-2010-2641
and CVE-2010-2643 have been fixed in version 2.30.3-2 but the fix for
CVE-2010-2642 was incomplete. The final fix is present in version
2.30.3-2+squeeze1.

For the testing distribution (wheezy), this problem has been fixed in
version 3.0.2.

For the unstable distribution (sid), this problem has been fixed in
version 3.0.2.

We recommend that you upgrade your evince packages.
