Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management errors (CVE-ID: CVE-2009-1046)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an 'off-by-two memory error.' NOTE: it is not clear whether this issue crosses privilege boundaries.
Remediation
Install update from vendor's website.
