Pidgin Denial-of-Service Vulnerability

Pidgin is prone to a denial-of-service vulnerability because it fails to properly sanitize user-supplied input. Successful exploits will cause the affected application to crash, effectively denying service to legitimate users. Sending a filename that contains the maximum number of allowable characters and that includes the characters defined by the hex data below will crash the application: '26 23 38 32 32 37 3b 20 26 23 38 32 32 38 3b 20 26 23 38 32 32 39 3b 20 85'

Mitigation:

Input validation should be used to ensure that user-supplied data is properly sanitized.

Successful exploits will cause the affected application to crash, effectively denying service to legitimate users.

Pidgin 2.4.1 is vulnerable; other versions may also be affected.

NOTE: This issue was previously thought to be a subset of the vulnerability documented in BID 29956 (Pidgin 'msn_slplink_process_msg()' Multiple Integer Overflow Vulnerabilities), but has been given its own record to properly document the vulnerability. 

Sending a filename that contains the maximum number of allowable characters and that includes the characters defined by the hex data below will crash the application.
