Linux kernel overlapping VMA gain privileges

linux-vma-gain-privileges (18886) The risk level is classified as HighHigh Risk

Description:

Linux kernel could allow a local attacker to gain elevated privileges on the system, caused by improper checking of overlapping virtual memory address (VMA) allocations when processing ELF binaries on IA64 systems. By creating a specially-crafted binary, a local attacker could gain root privileges or cause the system to crash, once the malicious binary is executed.


Consequences:

Gain Privileges

Remedy:

Apply the patch for this vulnerability, available from the BitKeeper Web site. See References.

For Red Hat Linux:
Upgrade to the latest kernel package, as listed below. Refer to RHSA-2005:043-13 or RHSA-2005:017-14 for more information. See References.
