Description Mark J. Cox 2005-09-07 10:09:46 UTC

"Memory leak in the seq_file implemenetation in the SCSI procfs interface (sg.c)
in Linux kernel 2.6.13 and earlier allows local users to cause a denial of
service (memory consumption) via certain repeated reads from the
/proc/scsi/sg/devices file, which is not properly handled when the next()
iterator returns NULL or an error."

Affects: RHEL4
