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.
