Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) NULL pointer dereference

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

Description

The 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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Tcpreplay: 3.4.2 - 4.3.1

2) NULL pointer dereference

EUVDB-ID: #VU17826

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-2019-8377

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference condition that exists in the get_ipv6_l4proto()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.

Mitigation
