Detailsinfo

A vulnerability classified as critical has been found in fsplib up to 0.8. This affects the function fsp_readdir_native in the library fsplib.c of the file fsplib.c. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple stack-based buffer overflows in fsplib.c in fsplib before 0.9 might allow remote attackers to execute arbitrary code via (1) a long filename that is not properly handled by the fsp_readdir_native function when MAXNAMLEN is greater than 255, or (2) a long d_name directory (dirent) field in the fsp_readdir function.

The weakness was released 07/23/2007 (Website). It is possible to read the advisory at fsp.cvs.sourceforge.net. This vulnerability is uniquely identified as CVE-2007-3962 since 07/25/2007. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.
