TITLE

tcpdump Vulnerable to out-of-bounds reading

DESCRIPTION

In tcpdump 4.9.2, a stack-based buffer over-read exists in the print_prefix function of print-hncp.c via crafted packet data because of missing initialization. tcpdump Contains an out-of-bounds vulnerability.Information may be obtained. TcpDump can completely intercept the data packets transmitted in the network for analysis. It supports filtering for the network layer, protocol, host, network or port, and provides logical statements such as and, or, not to help you remove useless information. The vulnerability stems from a lack of initialization. Tcpdump is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. An attacker can exploit this issue to execute arbitrary code in the context of an affected system. Failed exploit attempts may result in a denial-of-service condition; this can result in the attacker gaining complete control of the affected system. Tcpdump version 4.9.2 is vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Low: tcpdump security update Advisory ID: RHSA-2019:3976-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:3976 Issue date: 2019-11-26 CVE Names: CVE-2018-19519 ==================================================================== 1.
