SB2019031217 - Fedora 30 update for tcpreplay

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

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

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)

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)

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)

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)

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.
