Package : log2mail
Vulnerability : format string
Problem-Type : local/remote
Debian-specific: no
CVE Ids : CAN-2004-0450
jaguar@felinemenace.org
discovered a format string vulnerability in log2mail, whereby a
user able to log a specially crafted message to a logfile monitored
by log2mail (for example, via syslog) could cause arbitrary code to
be executed with the privileges of the log2mail process. By
default, this process runs as user ‘log2mail’, which is a member of
group ‘adm’ (which has access to read system logfiles).
CAN-2004-0450: log2mail format string vulnerability via
syslog(3) in printlog()
For the current stable distribution (woody), this problem has
been fixed in version 0.2.5.2.
For the unstable distribution (sid), this problem will be fixed
soon.
We recommend that you update your log2mail package.

Debian Security Advisory DSA 514-1 security@debian.org

Package : kernel-source-2.2.20, kernel-image-2.2-sparc
Vulnerability : failing function and TLB flush
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2004-0077
CERT advisory : VU#981222
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 flushing the TLB
(Translation Lookaside Buffer, an address cache) too early it is
possible for an attacker to trigger a local root exploit.
The attack vectors for 2.4.x and 2.2.x kernels are exclusive for
the respective kernel series, though. We formerly believed that the
exploitable vulnerability in 2.4.x does not exist in 2.2.x which is
still true. However, it turned out that a second (sort of)
vulnerability is indeed exploitable in 2.2.x, but not in 2.4.x,
with a different exploit, of course.
For the stable distribution (woody) these problems have been
fixed in version 9woody1 of Linux 2.2 kernel images for the sparc
architecture and in version 2.2.20-5woody3 of Linux 2.2.20
source.
For the unstable distribution (sid) these problems have been
fixed in version 9.1 of Linux 2.2 kernel images for the sparc
architecture.
This problem has been fixed for other architectures already.
We recommend that you upgrade your Linux kernel package.
