Candidate: CVE-2009-1046
PublicDate: 2009-03-23
References:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1046
http://www.ubuntu.com/usn/usn-751-1
Description:
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.
Ubuntu-Description:
The virtual consoles did not correctly handle certain UTF-8 sequences.
A local attacker on the physical console could exploit this to cause a
system crash, leading to a denial of service.
