SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :
- CVE-2007-0005 Daniel Roethlisberger discovered two buffer overflows in the cm4040 driver for the Omnikey CardMan 4040 device. A local user or malicious device could exploit this to execute arbitrary code in kernel space.
- CVE-2007-0958 Santosh Eraniose reported a vulnerability that allows local users to read otherwise unreadable files by triggering a core dump while using PT_INTERP. This is related to CVE-2004-1073.
- CVE-2007-1357 Jean Delvare reported a vulnerability in the appletalk subsystem. Systems with the appletalk module loaded can be triggered to crash by other systems on the local network via a malformed frame.
- CVE-2007-1592 Masayuki Nakagawa discovered that flow labels were inadvertently being shared between listening sockets and child sockets. This defect can be exploited by local users to cause a DoS (Oops).
SolutionUpgrade the kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.
This problem has been fixed in the stable distribution in version 2.6.18.dfsg.1-12etch1.
The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :
Debian 4.0 (etch) fai-kernels 1.17etch1 user-mode-linux 2.6.18-1um-2etch1 Updated packages for the mips and mipsel architectures are not yet available. They will be provided later.
