Synopsis

A buffer overflow vulnerability in Pan may allow remote attacker to

Background

Pan is a newsreader for the GNOME desktop.

Affected packages

  -------------------------------------------------------------------
   Package       /  Vulnerable  /                         Unaffected

Description

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

Impact

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

There is no known workaround at this time.

Resolution

All Pan users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose &quot;&gt;=net-nntp/pan-0.132-r3&quot;
