libxml2 vulnerability

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

  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 8.04 LTS

Summary:

libxml2 could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:

  • libxml2: GNOME XML library

Details:

Chris Evans discovered that libxml2 incorrectly handled memory allocation.
If an application using libxml2 opened a specially crafted XML file, an
attacker could cause a denial of service or possibly execute code as the
user invoking the program.

Update instructions:

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

Ubuntu 11.04:
libxml2 2.7.8.dfsg-2ubuntu0.1

Ubuntu 10.10:
libxml2 2.7.7.dfsg-4ubuntu0.2

Ubuntu 10.04 LTS:
libxml2 2.7.6.dfsg-1ubuntu1.2

Ubuntu 8.04 LTS:
libxml2 2.6.31.dfsg-2ubuntu1.6

After a standard system update you need to restart your session to make
all the necessary changes.
