CVE-2009-3547 (NULL pointer dereference and system crash)
Nov 9th
Synopsis: “Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.”
Debian 5.x systems suffer from this vulnerability (with or without Wine installed), and the fix is easy.
At a root shell, do the following:-
sysctl -w vm.mmap_min_addr="1024"
# make it persistent cat <<EOF > /etc/sysctl.d/mmap_min_addr.conf # Prevent http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3547 vm.mmap_min_addr=1024 EOF
