PeerCast: Buffer overflow — GLSA 200807-11

A buffer overflow vulnerability in PeerCast may allow for the remote execution of arbitrary code.

Affected Packages

media-sound/peercast on all architectures
Affected versions < 0.1218-r1
Unaffected versions >= 0.1218-r1

Background

PeerCast is a client and server for P2P-radio networks.

Description

Nico Golde reported a boundary error in the HTTP::getAuthUserPass() function when processing overly long HTTP Basic authentication requests.

Impact

A remote attacker could send a specially crafted HTTP request to the vulnerable server, 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 PeerCast users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1218-r1"
