CVE-2006-4253 – Mozilla Firefox 1.0.x - JavaScript Handler Race Condition Memory Corruption

https://notcve.org/view.php?id=CVE-2006-4253

Concurrency vulnerability in Mozilla Firefox 1.5.0.6 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via multiple Javascript timed events that load a deeply nested XML file, followed by redirecting the browser to another page, which leads to a concurrency failure that causes structures to be freed incorrectly, as demonstrated by (1) ffoxdie and (2) ffoxdie3. NOTE: it has been reported that Netscape 8.1 and K-Meleon 1.0.1 are also affected by ffoxdie. Mozilla confirmed to CVE that ffoxdie and ffoxdie3 trigger the same underlying vulnerability. NOTE: it was later reported that Firefox 2.0 RC2 and 1.5.0.7 are also affected. Vulnerabilidad de concurrencia en Mozilla Firefox 1.5.0.6 y anteriores permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección mediante múltiples eventos Javascript temporizados que cargan un archivo XML profundamente anidado, seguido por una redirección del navegador hacia ora página, lo cual lleva a un fallo de concurencia que provoca que se liberen estructuras incorrectamente, como ha sido demostrado por (1) ffoxdie y (2) ffoxdie3. • https://www.exploit-db.com/exploits/28380 ftp://patches.sgi.com/support/free/security/advisories/20060901-01-P.asc http://lcamtuf.coredump.cx/ffoxdie.html http://lcamtuf.coredump.cx/ffoxdie3.html http://secunia.com/advisories/21513 http://secunia.com/advisories/21906 http://secunia.com/advisories/21915 http://secunia.com/advisories/21916 http://secunia.com/advisories/21939 http://secunia.com/advisories/21940 http://secunia.com/advisories/21949 http://secunia.com/advisories&#x • CWE-264: Permissions, Privileges, and Access Controls •
