Description:
Some vulnerabilities have been reported in the Linux kernel, which potentially can be exploited by malicious, local users to disclose certain sensitive information, cause a DoS (Denial of Service) and gain escalated privileges, or by malicious people to cause a DoS.
1) A boundary error in "sendmsg()" when copying 32bit "msg_control" contents from user-space to the kernel can be exploited to cause a buffer overflow. This may allow a malicious user to gain root privileges and execute arbitrary code with kernel privileges.
The vulnerability has been reported in version 2.4.21 and 2.6.9. Other versions may also be affected.
2) An error in the "raw_sendmsg()" function may allow a malicious user to read kernel memory contents and disclose certain information, or to manipulate certain hardware state to cause a DoS.
The vulnerability has been reported in the 2.6 kernel branch.
3) An error in performing boundary checks in the standard multi-block cipher processors can be exploited to cause a kernel panic in an IPSec environment when handling packets with a block size that is not multiple of "bsize".
The vulnerability has been reported in version 2.6.13. Prior versions may also be affected.
