CVSS v2.0
7.2
High
| Vector | AV:L/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.9-rc7
Debian GNU/Linux (affected versions not specified)
Description
The issue affects the Linux kernel and Debian GNU/Linux operating system, allowing a local attacker to exploit multiple vulnerabilities, potentially leading to breaches of confidentiality, integrity, and availability of protected information. The
vcc recvmsg function in net/atm/common.c does not properly initialize a certain length variable, enabling local users to obtain sensitive information from the kernel stack via a crafted recvmsg or recvfrom system call.Recommendations
For Linux kernel versions prior to 3.9-rc7, update to version 3.9-rc7 or later to resolve the issue.
For Debian GNU/Linux, at the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the
vcc recvmsg function in the kernel to minimize the risk of exploitation.Information Disclosure
