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: 5.9

Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-1970, CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)
Content containing a malicious Scalable Vector Graphics (SVG) image file could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
Two flaws were found in the way Thunderbird rendered certain images using WebGL. Malicious content could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-3967, CVE-2012-3968)
A flaw was found in the way Thunderbird decoded embedded bitmap images in Icon Format (ICO) files. Content containing a malicious ICO file could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-3966)
A flaw was found in the way the 'eval' command was handled by the Thunderbird Error Console. Running 'eval' in the Error Console while viewing malicious content could possibly cause Thunderbird to execute arbitrary code with the privileges of the user running Thunderbird.
An out-of-bounds memory read flaw was found in the way Thunderbird used the format-number feature of XSLT (Extensible Stylesheet Language Transformations). Malicious content could possibly cause an information leak, or cause Thunderbird to crash. (CVE-2012-3972)
A flaw was found in the location object implementation in Thunderbird.
Malicious content could use this flaw to possibly allow restricted content to be loaded. (CVE-2012-3978)
