CVE-2003-1234: Integer Overflow

Published Dec 31, 2003
·
Updated

Integer overflow in the fcount counter in FreeBSD before 4.2 through 5.0 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via multiple calls to (1) fpathconf and (2) lseek, which do not properly decrement fcount through a call to fdrop.
