Title : Linux Kernel "raw_sendmsg()" and "sendmsg()" Local Vulnerabilities
VUPEN ID : VUPEN/ADV-2005-1701
CVE ID : CVE-2005-2490 - CVE-2005-2492
CWE ID : CWE-
Rated as : Moderate Risk 
Remotely Exploitable : No
Locally Exploitable : Yes
Release Date : 2005-09-11
|
Two vulnerabilities were identified in Linux Kernel, which could be exploited by local attackers to obtain elevated privileges, cause a denial of service, or disclose sensitive information.
The first issue is due to an error in "raw_sendmsg()", which could be exploited by local attackers to disclose the contents of kernel memory or cause a denial of service by manipulating hardware state.
The second flaw is due to a buffer overflow error in "sendmsg()" when copying 32bit "msg_control" contents to kernel, which could be exploited by local attackers to execute arbitrary commands with "root" privileges.
