Peercast procConnectArgs function buffer overflow
| peercast-url-bo (25113) |  High Risk |
Description:
Peercast is vulnerable to a stack-based buffer overflow, caused by improper bounds checking of the user supplied input by the procConnectArgs function in servmgr.cpp. By sending a specially-crafted HTTP GET request with an overly long parameter, a remote attacker could overflow a buffer and execute arbitrary code on the system.
Platforms Affected:
- Gentoo, Linux
- peercast.org, Peercast 0.1215 and prior
Remedy:
Upgrade to the latest version of Peercast (0.1217 or later), available from the Peercast Web site. See References.
For Gentoo Linux:
Refer to Gentoo Linux Security Announcement GLSA 2006-03-17 for patch, upgrade, or suggested workaround information. See References.
Consequences:
