CSCvt06879 | Snort cores constantly with VDB 331 |
Vulnerability Database (VDB) update 331 for Firepower Threat Defense (FTD) might cause Snort to restart when it encounters SSL traffic due to memory corruption.
FTD software uses the VDB updates to provide protection from known vulnerabilities to which hosts might be susceptible, as well as fingerprints for operating systems, clients, and applications. Customers are encouraged to configure the scheduling of automatic VDB updates to maximize protection from any new attack patterns.
If VDB update 331 is downloaded to FTD, customers might experience a Snort restart when it encounters SSL traffic due to a memory corruption issue. Note that VDB update 331 has been removed from the Cisco server to prevent additional customer risk exposure.
The Firepower Management Center will provide notification that "The Primary Detection Engine process terminated unexpectedly 1 time(s)" after FTD is upgraded to VDB 331. Customers might also experience issues with network traffic due to Snort restarts and memory corruption issues.
Use Firepower Management Center to download and install VDB update 332 or later. See the Cisco Firepower Management Center Configuration Guide for your version of Firepower software for instructions on how to install VDB updates.
