SuSE Linux AG has detected five security vulnerabilities in the version of the Squid web cache software included in its Linux distribution, the company announced Tuesday.
Squid is a high-performance proxy cache server software for Web clients, supporting FTP (File Transfer Protocol), gopher and HTTP (Hypertext Transfer Protocol) data objects. Unlike traditional caching software, Squid handles all requests in a single, nonblocking, I/O-driven process.
The severity of the errors in the package ranges from harmless to critical, according to SuSE in Nürnberg, Germany. The company points to vulnerabilities in gopher clients and the FTP directory parsing code, which could "remotely execute code introduced by attackers."
"Every open source vendor with Squid software, which is the most widely used cache proxy package, is affected," said Roman Drahtmüller, director of SuSE's security team.
