Description:
Alejandro Hernandez Hernandez has reported a vulnerability in Snort, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error in the "PrintTcpOptions()" function located in snort-2.4.0/src/log.c. This can be exploited to cause Snort to crash via a TCP/IP packet containing a malformed TCP SACK option.
Successful exploitation requires that Snort is configured to run in verbose mode (using the switch -v).
The vulnerability has been reported in version 2.4.0. Prior versions may also be affected.
