Detailsinfo

A vulnerability classified as critical has been found in FreeBSD 6.1 (Operating System). This affects the function ffs_rdextattr of the component Filesystem. The manipulation with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on availability. The summary by CVE is:

Integer overflow in the ffs_rdextattr function in FreeBSD 6.1 allows local users to cause a denial of service (kernel panic) and trigger a heap-based buffer overflow via a crafted UFS filesystem, a different vulnerability than CVE-2006-5679. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem.

The weakness was released 11/09/2006 (Website). The advisory is shared at lists.freebsd.org. This vulnerability is uniquely identified as CVE-2006-5824 since 11/08/2006. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at X-Force (30144). Entry connected to this vulnerability is available at VDB-33199. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
