Multiple stack-based buffer overflows in Sarg might allow attackers to execute arbitrary code via unknown vectors, probably a crafted Squid log file.

The arrayShrink function (lib/Array.c) in Squid 2.6.STABLE17 allows attackers to cause a denial of service (process exit) via unknown vectors that cause an array to shrink to 0 entries, which triggers an assert error. NOTE: this issue is due to an incorrect fix for CVE-2007-6239.

Stack-based buffer overflow in the useragent function in useragent.c in Squid Analysis Report Generator (Sarg) 2.2.3.1 allows remote attackers to execute arbitrary code via a long Squid proxy server User-Agent header. NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in Squid Analysis Report Generator (Sarg) 2.2.3.1 allows remote attackers to inject arbitrary web script or HTML via the User-Agent header, which is not properly handled when displaying the Squid proxy log. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The "cache update reply processing" functionality in Squid 2.x before 2.6.STABLE17 and Squid 3.0 allows remote attackers to cause a denial of service (crash) via unknown vectors related to HTTP headers and an Array memory leak during requests for cached objects.

Unspecified vulnerability in Office Efficiencies SafeSquid 4.1.x has unknown impact and attack vectors, related to a "serious security flaw," possibly specific to Linux.

The clientProcessRequest() function in src/client_side.c in Squid 2.6 before 2.6.STABLE12 allows remote attackers to cause a denial of service (daemon crash) via crafted TRACE requests that trigger an assertion error.

The aclMatchExternal function in Squid before 2.6.STABLE7 allows remote attackers to cause a denial of service (crash) by causing an external_acl queue overload, which triggers an infinite loop.

squid/src/ftp.c in Squid before 2.6.STABLE7 allows remote FTP servers to cause a denial of service (core dump) via crafted FTP directory listing responses, possibly related to the (1) ftpListingFinish and (2) ftpHtmlifyListEntry functions.

Unspecified vulnerability in Squid on SUSE Linux 9.0 allows remote attackers to cause a denial of service (crash) via HTTPs (SSL).
