Several remote vulnerabilities have been discovered in the Tomcat servlet and JSP engine. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2007-3382 It was discovered that single quotes (') in cookies were treated as a delimiter, which could lead to an information leak. CVE-2007-3385 It was discovered that the character sequence \ in cookies was handled incorrectly, which could lead to an information leak. CVE-2007-3386 It was discovered that the host manager servlet performed insufficient input validation, which could lead to cross-site scripting. CVE-2007-5342 It was discovered that the JULI logging component did not restrict its target path, resulting in potential denial of service through file overwrites. CVE-2007-5461 It was discovered that the WebDAV servlet is vulnerable to absolute path traversal. For the stable distribution (etch), these problems have been fixed in version 5.5.20-2etch1. The old stable distribution (sarge) doesn't contain tomcat5.5. The unstable distribution (sid) will be fixed soon. We recommend that you upgrade your tomcat5.5 packages.
