Description
This security bulletin contains information about 1 vulnerability.
1) Input validation error (CVE-ID: CVE-2011-1476)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 5.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Integer underflow in the Open Sound System (OSS) subsystem in the Linux kernel before 2.6.39 on unspecified non-x86 platforms allows local users to cause a denial of service (memory corruption) by leveraging write access to /dev/sequencer.
Remediation
Install update from vendor's website.
