Debian GNU/Liux Advisory: kernel (2.4.16)Apr 28, 2004, 03:58 (0 Talkback[s])
Package : kernel-source-2.4.16 kernel-patch-2.4.16-arm
Several serious problems have been discovered in the Linux kernel. This update takes care of Linux 2.4.16 for the ARM architecture. The Common Vulnerabilities and Exposures project identifies the following problems that will be fixed with this update:
The kernel module loader allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel
A vulnerability has been discovered in the R128 drive in the Linux kernel which could potentially lead an attacker to gain unauthorised privileges. Alan Cox and Thomas Biege developed a correction for this
Arjan van de Ven discovered a stack-based buffer overflow in the ncp_lookup function for ncpfs in the Linux kernel, which could lead an attacker to gain unauthorised privileges. Petr Vandrovec developed a correction for this.
zen-parse discovered a buffer overflow vulnerability in the ISO9660 filesystem component of Linux kernel which could be abused by an attacker to gain unauthorised root access. Sebastian Krahmer and Ernie Petrides developed a correction for this.
Solar Designer discovered an information leak in the ext3 code of Linux. In a worst case a local attacker could obtain sensitive information (such as cryptographic keys in another worst case) which would otherwise never hit disk media. Theodore Ts'o developed a correction for this.
Andreas Kies discovered a denial of service condition in the Sound Blaster driver in Linux. He also developed a correction for this.
These problems are also fixed by upstream in Linux 2.4.26 and will be fixed in Linux 2.6.6.
The following security matrix explains which kernel versions for which architectures are already fixed and which will be removed instead.
We recommend that you upgrade your kernel packages immediately, either with a Debian provided kernel or with a self compiled one.
will fetch the file for you
will install the referenced file.
If you are using the apt-get package manager, use the line for sources.list as given below:
will update the internal database apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the footer to the proper configuration.
