Summary

Off-by-one error in the fsp_readdir_r function in fsplib.c in fsplib before 0.9 allows remote attackers to cause a denial of service via a directory entry whose length is exactly MAXNAMELEN, which prevents a terminating null byte from being added. Vendor has supplied upgrade patch: http://sourceforge.net/project/showfiles.php?group_id=93841&package_id=139615&release_id=526638

    descriptionA Secunia Advisory reports : fsplib can be exploited to compromise an application using the library. 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. 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.
