Name of the Vulnerable Software and Affected Versions libpcap versions prior to 1.9.1

Description The issue is related to a denial of service caused by a NULL pointer dereference and daemon crash in the rpcapd/daemon.c component of the libpcap library. This can occur if a crypt() call fails. The vulnerability can be exploited by a remote attacker to cause a denial of service.

Recommendations For versions prior to 1.9.1, update to version 1.9.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the rpcapd/daemon.c component to minimize the risk of exploitation.
