Description Mark J. Cox (Product Security) 2003-01-29 08:11:58 EST
The BGP decoding routines for tcpdump used incorrect bounds checking when
copying data. This could be abused by introducing malicious traffic on a sniffed
network for a denial of service attack against tcpdump, or possibly even remote
code execution.

RHSA-2002:094 patched CAN-2002-0380 with tcpdump-3.6.2-11
AS/RHSA-2002:121 patched CAN-2002-0380 with tcpdump-3.6.2-11

This hasn't been fixed in anything but the Advanced Series. It should be reopened.
Comment 4 Mark J. Cox (Product Security) 2003-03-08 09:16:05 EST
This bug is filed against the Advanced Server product and therefore should be
closed.  There might be a bug already open against the base product for this
security issue, but even if not an errata is in progress for the base.
