Red Hat Bugzilla – Bug 151297
CAN-2005-0469 slc_add_reply() Buffer Overflow Vulnerability
Last modified: 2007-11-30 17:07:17 EST
The vulnerability specifically exists in the handling of the LINEMODE
suboptions, in that there is no size check made on the output, which is stored
in a fixed length buffer. By sending a specially constructed reply containing a
large number of SLC (Set Local Character) commands, it is possible to overflow
this buffer with server supplied data.
This issue also affects RHEL2.1 and RHEL3
