CVE-2005-2459: Null Pointer Dereference

Published Aug 22, 2005
·
Updated

The huftbuild function in inflate.c in the zlib routines in the Linux kernel before 2.6.12.5 returns the wrong value, which allows remote attackers to cause a denial of service (kernel crash) via a certain compressed file that leads to a null pointer dereference, a different vulnerability than CVE-2005-2458.
