Several security related problems have been discovered in the Linux kernel which may lead to a denial of service or even the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
A buffer overflow in NFS readlink handling allows a malicious remote server to cause a denial of service.
Diego Calleja Garcia discovered a buffer overflow in the DVD handling code that could be exploited by a specially crafted DVD USB storage device to execute arbitrary code.
A bug in the SCSI driver allows a local user to cause a denial of service.
Patrick McHardy discovered a bug in the SNMP NAT helper that allows remote attackers to cause a denial of service.
A race condition in the socket buffer handling allows remote attackers to cause a denial of service.
Wei Wang discovered a bug in the SCTP implementation that allows local users to cause a denial of service and possibly gain root privileges.
David Miller reported a problem with the fix for CVE-2006-3745 that allows local users to crash the system via an SCTP socket with a certain SO_LINGER value.
The following matrix explains which kernel version for which architecture fixes the problem mentioned above:
| stable (sarge) | |
|---|---|
| Source | 2.4.27-10sarge4 |
| Alpha architecture | 2.4.27-10sarge4 |
| ARM architecture | 2.4.27-2sarge4 |
| Intel IA-32 architecture | 2.4.27-10sarge4 |
| Intel IA-64 architecture | 2.4.27-10sarge4 |
| Motorola 680x0 architecture | 2.4.27-3sarge4 |
| MIPS architectures | 2.4.27-10.sarge4.040815-1 |
| PowerPC architecture | 2.4.27-10sarge4 |
| IBM S/390 | 2.4.27-2sarge4 |
| Sun Sparc architecture | 2.4.27-9sarge4 |
| FAI | 1.9.1sarge4 |
| mindi-kernel | 2.4.27-2sarge3 |
| kernel-image-speakup-i386 | 2.4.27-1.1sarge3 |
| systemimager | 3.2.3-6sarge3 |
For the unstable distribution (sid) these problems won't be fixed anymore in the 2.4 kernel series.
We recommend that you upgrade your kernel package 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.
