Last modified

CVE-2003-1234 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
