F5 Networks BIG-IP : OpenSSL vulnerability (K37526132)

high Nessus Plugin ID 97361

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to 1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k. (CVE-2017-3731)

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K37526132.
