> Product         : Cisco SCA 11000 Series Secure Content Accelerator
> Product URL     : http://www.cisco.com/warp/public/cc/pd/cxsr/ps2083/
> CVE             : CAN-2002-0656
> Software release: All current releases
> Vendor status   : PSIRT and TAC notified 2002/09/17, last update 2002/09/24
> Patch status    : No patch available

> Attempts to exploit the vulnerability described in CAN-2002-0656 cause the
> SCA 11000 (all tested software releases) to spontaneously reboot, resulting
> in at least a denial of service.  This product incorporates code from an
> older OpenSSL release, and thus shares the same vulnerability.  There is no
> known means to work around this issue, short of disabling SSL services on
> the system.

> Cisco's Secure Content Accelerator is closely related to SonicWall's SSL
> offloader product.  The SonicWall product was also vulnerable, and a
> statement and fix were issued promptly:

> http://www.sonicwall.com/support/security_advisories/security_advisory-openSSL.html

> No official fix is as yet available from Cisco for this issue, and no
> advisory has been released.  Impact is likely equivalent to impact on the
> SonicWall product.

> Cisco PSIRT publishes advisories here:
