Description Mark J. Cox 2004-07-05 10:58:41 UTC 
Reported to Bugtraq on Jun23.  

An integer overflow in the ubsec_keysetup function for Linux Broadcom
5820 cryptonet driver allows local users to cause a denial of service
(crash) and possibly execute arbitrary code via a negative
add_dsa_buf_bytes variable, which leads to a buffer overflow.

Patch applies same security fixes and cleanup that was applied to RHEL3 in bug
127258.
Comment 4 Mark J. Cox 2004-12-20 15:56:47 UTC 
bcm5820 driver is not functional on rhel2.1-ia64 therefore has no
security impact.  closing.
