Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU17825
Risk: Low
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-8376
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference condition in the get_layer4_v6() function, as defined in the get.c source code file. A remote attacker can send a specially crafted packet capture (pcap) file to the tcpreplay-edit binary, trigger a segmentation fault and cause a DoS condition.
