Description:
A vulnerability was reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create specially crafted HTML that, when loaded by the target user, will trigger a buffer overflow or memory access error and execute arbitrary code on the target system. The code will run with the privileges of the target user.
A JavaScript regular expression that contains a minimal quantifier can trigger this flaw [CVE-2006-4565]. Priit Laes reported this vulnerability.
A regular expression that ends with a backslash inside of an unterminated character set (e.g. "[\\") can trigger an overflow [CVE-2006-4566]. CanadianGuy, Girts Folkmanis, and Catalin Patulea reported this vulnerability.
Timing-dependent Javascript cases can trigger this flaw [CVE-2006-4253]. Jonathan Watt and Michal Zalewski independently reported this vulnerability.
Various cases can trigger memory corruption, which may potentially lead to arbitrary code execution [CVE-2006-4571]. Bernd Mielke, Georgi Guninski, Igor Bukanov, Jesse Ruderman, Martijn Wargers, Mats Palmgren, Olli Pettay, shutdown, and Weston Carloss reported these vulnerabilities.
