Peercast HTTP::getAuthUserPass() buffer overflow
| peercast-httpgetauthuserpass-bo (42092) |  High Risk |
Description:
Peercast is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the HTTP::getAuthUserPass() function when the authorization type is set to HTTP Basic. By sending a specially-crafted authentication request using an overly long HTTP Basic authentication string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Note: This vulnerability also affects GNOME PeerCast.
Platforms Affected:
- Debian, Debian Linux 4.0
- Gentoo, Linux
- GNOME, PeerCast 0.1217
- peercast.org, PeerCast 0.1218
Remedy:
No remedy available as of July 6, 2008.
Consequences:
