Linux kernel sendmsg function buffer overflow
| kernel-sendmsg-bo (22217) |  High Risk |
Description:
Linux kernel is vulnerable to a stack-based buffer overflow caused by improper bounds checking in the sendmsg() function. This occurs when copying 32-bit msg_control contents from user-space to the kernel. A local attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with kernel privileges.
Consequences:
Gain Access
Remedy:
For Debian GNU/Linux:
Refer to DSA-1017-1 for patch, upgrade, or suggested workaround information. See References.
For Red Hat Linux:
Refer to RHSA-2005:514-46 or RHSA-2005:663-19 for patch, upgrade, or suggested workaround information. See References.
For Ubuntu Linux:
Refer to USN-178-1 for patch, upgrade, or suggested workaround information. See References.
For SUSE Linux:
Refer to SUSE Security Announcement SUSE-SA:2005:068 for patch, upgrade, or suggested workaround information. See References.
For other distributions:
Contact your vendor for upgrade or patch information.
