Ubuntu 6.06 LTS : firefox vulnerabilities (USN-351-1)

critical Nessus Plugin ID 27931

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious web page containing JavaScript. (CVE-2006-4253, CVE-2006-4565, CVE-2006-4566, CVE-2006-4568, CVE-2006-4569 CVE-2006-4571)

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)

Jon Oberheide reported a way how a remote attacker could trick users into downloading arbitrary extensions with circumventing the normal SSL certificate check. The attacker would have to be in a position to spoof the victim's DNS, causing them to connect to sites of the attacker's choosing rather than the sites intended by the victim. If they gained that control and the victim accepted the attacker's cert for the Mozilla update site, then the next update check could be hijacked and redirected to the attacker's site without detection.
(CVE-2006-4567).

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.

Solution

Update the affected packages.
