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. 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.
SuSE has released patches, which can be found, together with the company's security announcement, at: www.suse.de/de/support/security/2002_025_squid_txt.html
