Ubuntu Security Notice USN-1310-1
December 19, 2011

libarchive vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

libarchive could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libarchive: Library to read/write archive files

Details:

It was discovered that libarchive incorrectly handled certain ISO 9660
image files. If a user were tricked into using a specially crafted
ISO 9660 image file, a remote attacker could cause libarchive to crash or
possibly execute arbitrary code with user privileges. (CVE-2011-1777)

It was discovered that libarchive incorrectly handled certain tar archive
files. If a user were tricked into using a specially crafted tar file, a
remote attacker could cause libarchive to crash or possibly execute
arbitrary code with user privileges. (CVE-2011-1778)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  libarchive1                     2.8.4-1ubuntu0.11.10.1

Ubuntu 11.04:
  libarchive1                     2.8.4-1ubuntu0.11.04.1

Ubuntu 10.10:
  libarchive1                     2.8.4-1ubuntu0.10.10.1

Ubuntu 10.04 LTS:
  libarchive1                     2.8.0-2ubuntu0.1

In general, a standard system update will make all the necessary changes.
