Description
This security bulletin contains information about 1 security vulnerability.
1) Incorrect calculation (CVE-ID: CVE-2005-3356)
The vulnerability allows a local user to perform service disruption.
The mq_open system call in Linux kernel 2.6.9, in certain situations, can decrement a counter twice ('double decrement') as a result of multiple calls to the mntput function when the dentry_open function call fails, which allows local users to cause a denial of service (panic) via unspecified attack vectors.
Remediation
Install update from vendor's website.
