Description

This security bulletin contains information about 5 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2019-8376)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


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.


2) NULL pointer dereference (CVE-ID: CVE-2019-8377)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


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.


3) Segmentation fault (CVE-ID: CVE-2019-8381)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


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

The vulnerability exists due to an invalid memory access condition that exists in the do_checksumfunction, as defined in the checksum.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.


4) Out-of-bounds read (CVE-ID: CVE-2018-18407)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

A heap-based buffer over-read was discovered in the tcpreplay-edit binary of Tcpreplay 4.3.0 beta1, during the incremental checksum operation. The issue gets triggered in the function csum_replace4() in incremental_checksum.h, causing a denial of service.


5) Use-after-free (CVE-ID: CVE-2018-18408)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

A use-after-free was discovered in the tcpbridge binary of Tcpreplay 4.3.0 beta1. The issue gets triggered in the function post_args() at tcpbridge.c, causing a denial of service or possibly unspecified other impact.
