Description Vincent Danen 2011-04-12 22:02:44 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2011-1675 to
the following vulnerability:

Name: CVE-2011-1675
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1675
Assigned: 20110409
Reference: http://openwall.com/lists/oss-security/2011/03/04/9

mount in util-linux 2.19 and earlier attempts to append to the
/etc/mtab.tmp file without first checking whether resource limits
would interfere, which allows local users to trigger corruption of the
/etc/mtab file via a process with a small RLIMIT_FSIZE value, a
related issue to CVE-2011-1089.
