New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-3175, CVE-2010-3176, CVE-2010-3179, CVE-2010-3183, CVE-2010-3180)
A same-origin policy bypass flaw was found in Firefox. An attacker could create a malicious web page that, when viewed by a victim, could steal private data from a different website the victim has loaded with Firefox. (CVE-2010-3178)
A flaw was found in the script that launches Firefox. The LD_LIBRARY_PATH variable was appending a '.' character, which could allow a local attacker to execute arbitrary code with the privileges of a different user running Firefox, if that user ran Firefox from within an attacker-controlled directory. (CVE-2010-3182)
This update also provides NSS version 3.12.8 which is required by the updated Firefox version, fixing the following security issues :
It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode implementation for key exchanges in Firefox accepted DHE keys that were 256 bits in length. This update removes support for 256 bit DHE keys, as such keys are easily broken using modern hardware.
A flaw was found in the way NSS matched SSL certificates when the certificates had a Common Name containing a wildcard and a partial IP address. NSS incorrectly accepted connections to IP addresses that fell within the SSL certificate's wildcard range as valid SSL connections, possibly allowing an attacker to conduct a man-in-the-middle attack. (CVE-2010-3170)
After installing the update, Firefox must be restarted for the changes to take effect.
SolutionUpdate the affected packages.
