New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Several 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-2010-3169, CVE-2010-2762)

Several use-after-free and dangling pointer flaws were found in Firefox. 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-2010-2760, CVE-2010-2766, CVE-2010-2767, CVE-2010-3167, CVE-2010-3168)

Multiple buffer overflow flaws were found in Firefox. 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-2010-2765, CVE-2010-3166)

Multiple cross-site scripting (XSS) flaws were found in Firefox. A web page containing malicious content could cause Firefox to run JavaScript code with the permissions of a different website.
(CVE-2010-2768, CVE-2010-2769)

A flaw was found in the Firefox XMLHttpRequest object. A remote site could use this flaw to gather information about servers on an internal private network. (CVE-2010-2764)

Note: After installing this update, Firefox will fail to connect (with HTTPS) to a server using the SSL DHE (Diffie-Hellman Ephemeral) key exchange if the server's ephemeral key is too small. Connecting to such servers is a security risk as an ephemeral key that is too small makes the SSL connection vulnerable to attack.

If you encounter the condition where Firefox fails to connect to a server that has an ephemeral key that is too small, you can try connecting using a cipher suite with a different key exchange algorithm by disabling all DHE cipher suites in Firefox :

1) Type about:config in the URL bar and press the Enter key. 2) In the Filter search bar, type ssl3.dhe 3) For all preferences now presented, double-click the true value to change the value to false. 4) This change would affect connections to all HTTPS servers.

After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected packages.
