Debian Security Advisory DSA 276-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
April 3rd, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Packages : kernel-patch-2.4.17-s390, kernel-image-2.4.17-s390
Vulnerability : local privilege escalation
Problem-Type : local
Debian-specific: no
CVE Id : CAN-2003-0127
The kernel module loader in Linux 2.2 and Linux 2.4 kernels has a flaw
in ptrace. This hole allows local users to obtain root privileges by
using ptrace to attach to a child process that is spawned by the
kernel. Remote exploitation of this hole is not possible.
This advisory only covers kernel packages for the S/390 architecture.
Other architectures will be covered by separate advisories.
For the stable distribution (woody) this problem has been fixed in the
following versions:
kernel-patch-2.4.17-s390: version 0.0.20020816-0.woody.1.1
kernel-image-2.4.17-s390: version 2.4.17-2.woody.2.2
The old stable distribution (potato) is not affected by this problem
for this architecture since s390 was first released with Debian
GNU/Linux 3.0 (woody).
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you upgrade your kernel-images packages immediately.
Upgrade Instructions
