CVE-2011-1679

15
FAUCET Score

CVE-2011-1679 affects ncpfs versions 2.2.6 and earlier, where the ncpmount and ncpumount utilities fail to check resource limits before writing to /etc/mtab and /etc/mtab.tmp respectively. This oversight allows a local attacker with a small RLIMIT_FSIZE value to corrupt the /etc/mtab file. The vulnerability has a CVSS score of 3.3 (AV:L/AC:M/Au:N/C:P/I:P/A:N), indicating low severity with local access, medium attack complexity, and potential for partial confidentiality and integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
