New Squid packages are available which fix various issues.
Squid is a high-performance proxy caching server. The following summary describes the various issues found and fixed: Several buffer overflows have been found in the MSTN auth helper (msnt_auth) when configured to use denyusers or allowusers access control files. Several buffer overflows were found in the gopher client of Squid. It could be possible for a malicious gopher server to cause Squid to crash. A problem was found in the handling of the FTP data channel, possibly allowing abuse of the FTP proxy to bypass firewall rules or inject false FTP replies. Several possible buffer overflows were found in the code parsing FTP directories, which potentially allow for an untrusted FTP server to crash Squid. Thanks go to Olaf Kirch and the Squid team for notifying us of the problems and to the Squid team for providing patches. All users of Squid are advised to upgrade to these errata packages which contain patches to correct each of these issues.
