Description Vincent Danen 2011-04-12 22:22:45 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2011-1679 to
the following vulnerability:

Name: CVE-2011-1679
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1679
Assigned: 20110409
Reference: http://openwall.com/lists/oss-security/2011/03/04/9
Reference: https://bugzilla.redhat.com/show_bug.cgi?id=688980

ncpfs 2.2.6 and earlier attempts to use (1) ncpmount to append to the
/etc/mtab file and (2) ncpumount 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.
