CVE-2003-1234 Information

Description

Integer overflow in the f_count 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 f_count through a call to fdrop.
