Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

A buffer overflow vulnerability in Pan may allow remote attacker to
execute arbitrary code.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Pan is a newsreader for the GNOME desktop.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Pavel Polischouk reported a boundary error in the PartsBatch class when
processing .nzb files.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could entice a user to open a specially crafted .nzb
file, possibly resulting in the remote execution of arbitrary code with
the privileges of the user running the application.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Pan users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=3Dnet-nntp/pan-0.132-r3"
