wireshark: NULL pointer dereference resulting in a PVFS dissector crash
vendor_redhat·2018-11-27·CVSS 5.5
CVE-2018-19624 [MEDIUM] CWE-476 wireshark: NULL pointer dereference resulting in a PVFS dissector crash
wireshark: NULL pointer dereference resulting in a PVFS dissector crash
In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the PVFS dissector could crash. This was addressed in epan/dissectors/packet-pvfs2.c by preventing a NULL pointer dereference.
A NULL pointer dereference vulnerability in the PVFS dissector allows Wireshark to crash when parsing a specially crafted pcap file. A remote attacker could cause a denial of service to Wireshark by injecting malicious packets into the network that are automatically processed.
Statement: This issue did not affect the versions of wireshark as shipped with Red Hat Enterprise Linux 5, 6 and 7.
