USN-909-1: dpkg vulnerability

Releases

• Ubuntu 9.10
• Ubuntu 9.04
• Ubuntu 8.10
• Ubuntu 8.04
• Ubuntu 6.06

Packages

• dpkg -

Details

William Grant discovered that dpkg-source did not safely apply diffs
when unpacking source packages. If a user or an automated system were
tricked into unpacking a specially crafted source package, a remote
attacker could modify files outside the target unpack directory, leading
to a denial of service or potentially gaining access to the system.

Update instructions

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

Ubuntu 9.10

• dpkg-dev - 1.15.4ubuntu2.1

Ubuntu 9.04

• dpkg-dev - 1.14.24ubuntu1.1

Ubuntu 8.10

• dpkg-dev - 1.14.20ubuntu6.3

Ubuntu 8.04

• dpkg-dev - 1.14.16.6ubuntu4.1

Ubuntu 6.06

• dpkg-dev - 1.13.11ubuntu7.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
