CVE-2006-4253
Description
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.

Mozilla Firefox 1.0.x - JavaScript Handler Race Condition Memory Corruption
source: https://www.securityfocus.com/bid/19488/info
Mozilla Firefox is prone to a remote memory-corruption vulnerability. This issue is due to a race condition that may result in double-free or other memory-corruption issues.
Attackers may likely exploit this issue to execute arbitrary machine code in the context of the vulnerable application, but this has not been confirmed. Failed exploit attempts will likely crash the application.
Mozilla Firefox is vulnerable to this issue. Due to code reuse, other Mozilla products are also likely affected.
