TITLE:
fsplib Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA26184

VERIFY ADVISORY:
https://secunia.com/advisories/26184/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
fsplib 0.x
https://secunia.com/product/14856/

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.
