Detailsinfo

A vulnerability was found in Linux Kernel 2.6.23 (Operating System). It has been declared as critical. Affected by this vulnerability is the function hfs_cat_find_brec. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933.
