wireshark: ISAKMP dissector crash in epan/dissectors/packet-isakmp.c
In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the ISAKMP dissector could crash. This was addressed in epan/dissectors/packet-isakmp.c by properly handling the case of a missing decryption data block.

Certain Huawei products (AP2000;IPS Module;NGFW Module;NIP6300;NIP6600;NIP6800;S5700;SVN5600;SVN5800;SVN5800-C;SeMG9811;Secospace AntiDDoS8000;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG6000V;eSpace U1981) have a null pointer dereference vulnerability. The system dereferences a pointer that it expects to be valid, but is NULL. A local attacker could exploit this vulnerability by sending crafted parameters. A successful exploit could cause a denial of service and the process reboot.
Some Huawei smart phones have a null pointer dereference vulnerability. An attacker crafts specific packets and sends to the affected product to exploit this vulnerability. Successful exploitation may cause the affected phone to be abnormal.
An exploitable denial-of-service vulnerability exists in the Host Access Point Daemon (hostapd) on the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) wireless router. A SOAP request sent in an invalid sequence to the <WFAWLANConfig:1#PutMessage> service can cause a null pointer dereference, resulting in the hostapd service crashing. An unauthenticated attacker can send a specially-crafted SOAP request to trigger this vulnerability.
An exploitable denial-of-service vulnerability exists in the session handling functionality of the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) HTTP server. An HTTP request with an empty User-Agent string sent to a page requiring authentication can cause a null pointer dereference, resulting in the HTTP service crashing. An unauthenticated attacker can send a specially crafted HTTP request to trigger this vulnerability.
QEMU: NULL pointer dereference in hw/sparc64/sun4u.c leading to DoS
hw/sparc64/sun4u.c in QEMU 3.1.50 is vulnerable to a NULL pointer dereference, which allows the attacker to cause a denial of service via a device driver.
An issue was discovered in Foxit Reader and PhantomPDF before 9.4 on Windows. It is an Out-of-Bounds Read Information Disclosure and crash due to a NULL pointer dereference when reading TIFF data during TIFF parsing.
An issue was discovered in Foxit Reader and PhantomPDF before 9.4 on Windows. It is a NULL pointer dereference during PDF parsing.
ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a NULL pointer dereference. A remote unauthenticated attacker can crash the ELOG server by sending a crafted HTTP GET request.
libvirt: NULL pointer dereference after running qemuAgentCommand in qemuAgentGetInterfaces function
