[security-alerts] FW: [SA17934] Mozilla Firefox History Information Denial of Service Weakness



> 
> 
> TITLE:
> Mozilla Firefox History Information Denial of Service Weakness
> 
> SECUNIA ADVISORY ID:
> SA17934
> 
> VERIFY ADVISORY:
> http://secunia.com/advisories/17934/
> 
> CRITICAL:
> Not critical
> 
> IMPACT:
> DoS
> 
> WHERE:
> From remote
> 
> SOFTWARE:
> Mozilla Firefox 1.x

> 
> DESCRIPTION:
> ZIPLOCK has discovered a weakness in Mozilla Firefox, which can be
> exploited by malicious people to cause a DoS (Denial of Service).
> 
> The weakness is caused due to an error in the handling of large
> history information. This can be exploited to fill the history file
> "history.dat" with large history information by tricking a user into
> visiting a malicious web site with an overly large title (e.g. set
> via JavaScript).
> 
> Successful exploitation causes the browser to consume a large amount
> of CPU and memory resources on a vulnerable system when the affected
> browser is started up again after an attack. Users may have to remove
> the "history.dat" file in order to be able to use the affected
> browser.
> 
> The weakness has been confirmed in version 1.5. Other versions may
> also be affected.
> 
> SOLUTION:
> Configure Firefox to clear history information when closing the
> browser. This affects functionality.
