CVE-2007-3962

Description:
Some vulnerabilities in have been reported fsplib, which potentially can be exploited by malicious people to compromise an application using the library.
1) A boundary error exists in the processing of file names in fsp_readdir_native, which can be exploited to cause a stack-based buffer overflow if the defined MAXNAMLEN is bigger than 256.
2) A boundary error exists in the processing of directory entries in fsp_readdir, which can be exploited to cause a stack-based buffer overflow on systems with an insufficient size allocated for the d_name field of directory entries.
Successful exploitation may allow execution of arbitrary code.
NOTE: The fsp_readdir_r function does not properly NULL terminate the destination buffer when processing filenames that have MAXNAMLEN characters.
Solution:
Update to version 0.9.
