[GLSA-200703-04] Mozilla Firefox: Multiple vulnerabilities |
||
Mozilla Firefox: Multiple vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200703-04 (Mozilla Firefox: Multiple vulnerabilities) Tom Ferris reported a heap-based buffer overflow involving wide SVG stroke widths that affects Mozilla Firefox 2 only. Various researchers reported some errors in the JavaScript engine potentially leading to memory corruption. Mozilla Firefox also contains minor vulnerabilities involving cache collision and unsafe pop-up restrictions, filtering or CSS rendering under certain conditions. Impact A possible hacker could entice a user to view a specially crafted web page that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code. It is also possible for a possible hacker to spoof the address bar, steal information through cache collision, bypass the local files protection mechanism with pop-ups, or perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials. Workaround There is no known workaround at this time for all of these issues, but most of them can be avoided by disabling JavaScript.
