Description:
Debian has issued updated packages for the kernel. These fix multiple vulnerabilities, which are listed below.
1) The iBCS routines in Linux kernels 2.4.18 and earlier on x86 systems allow malicious, local users to kill arbitrary processes.
2) Linux Kernel 2.2 has been found vulnerable to a Denial of Service condition. It is possible for local users to read the memory used by certain programs by using "/proc/pid/mem" and "mmap()" function with a "PROT_READ" parameter.
3) Many ethernet NIC (Network Interface Card) device drivers pad frames with content from previous packets or kernel memory instead of using NULL-bytes. This may be exploited by malicious people to obtain potentially sensitive information by sending specially crafted packets to a vulnerable system.
4) An error in ptrace can be exploited by malicious, local users to escalate their privileges to "root" on a vulnerable system.
5) An error in the TCP/IP fragment reassembly handling, which allows malicious people to cause many hash table collisions leading to a DoS.
