Ubuntu 5.04 / 5.10 : mozilla vulnerabilities (USN-361-1)
Critical Nessus Plugin ID 27941
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionVarious flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious URL. (CVE-2006-2788, CVE-2006-3805, CVE-2006-3806, CVE-2006-3807, CVE-2006-3809, CVE-2006-3811, CVE-2006-4565, CVE-2006-4568, CVE-2006-4571)
A bug was found in the script handler for automatic proxy configuration. A malicious proxy could send scripts which could execute arbitrary code with the user's privileges. (CVE-2006-3808)
The NSS library did not sufficiently check the padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3 (which is widely used for CAs). This could be exploited to forge valid signatures without the need of the secret key. (CVE-2006-4340)
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
