-------------------------------------------------------------------------- Debian Security Advisory DSA 444-1 security@debian.org http://www.debian.org/security/ Martin Schulze February 20th, 2004 http://www.debian.org/security/faq --------------------------------------------------------------------------
Package : kernel-image-2.4.17-ia64 Vulnerability : missing function return value check Problem-Type : local Debian-specific: no CVE ID : CAN-2004-0077
Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap(2) system call. Due to missing function return value check of internal functions a local attacker can gain root privileges.
For the stable distribution (woody) this problem has been fixed in version 011226.16 of ia64 kernel source and images.
Other architectures are or will be mentioned in a separate advisory respectively or are not affected (m68k).
For the unstable distribution (sid) this problem will be fixed in version 2.4.24-3.
This problem is also fixed in the upstream version of Linux 2.4.25 and 2.6.3.
We recommend that you upgrade your Linux kernel packages immediately.
Upgrade Instructions --------------------
wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
If you are using the apt-get package manager, use the line for sources.list as given below:
apt-get update will update the internal database apt-get upgrade will install corrected packages
You may use an automated update by adding the resources from the footer to the proper configuration.
