Buffer overflow in the tcpcapinfo utility in Tcpreplay before 4.2.0 Beta 1 allows remote attackers to have unspecified impact via a pcap file with an over-size packet.
tcprewrite in tcpreplay before 4.1.2 allows remote attackers to cause a denial of service (segmentation fault) via a large frame, a related issue to CVE-2017-14266.
A security vulnerability has been detected in appneta tcpreplay 4.5.1. Impacted is the function calcsleeptime of the file sendpackets.c. Such manipulation leads to divide by zero. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 4.5.3-beta3 is recommended to address this issue. It is advisable to upgrade the affected component. The vendor confirms in a GitHub issue reply: "Was able to reproduce in 6fcbf03 but NOT 4.5.3-beta3."
A vulnerability was detected in appneta tcpreplay up to 4.5.1. Impacted is the function tcpeditpostargs of the file /src/tcpedit/parseargs.c. The manipulation results in null pointer dereference. The attack is only possible with local access. The exploit is now public and may be used. Upgrading to version 4.5.2-beta2 is recommended to address this issue. Upgrading the affected component is advised. The vendor explains, that he was "[a]ble to reproduce in 6fcbf03 but not in 4.5.2-beta2".
A flaw has been found in appneta tcpreplay up to 4.5.1. The affected element is the function fixipv6checksums of the file editpacket.c of the component tcprewrite. This manipulation causes use after free. The attack is restricted to local execution. The exploit has been published and may be used. Upgrading to version 4.5.2-beta3 is sufficient to fix this issue. It is advisable to upgrade the affected component.
A vulnerability has been found in appneta tcpreplay up to 4.5.1. The impacted element is the function getl2lenprotocol of the file get.c of the component tcprewrite. Such manipulation leads to use after free. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. Upgrading to version 4.5.2-beta3 is sufficient to resolve this issue. You should upgrade the affected component.
A vulnerability has been found in tcpreplay 4.5.1. This vulnerability affects the function maskcidr6 of the file cidr.c of the component tcpprep. The manipulation leads to heap-based buffer overflow. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The researcher is able to reproduce this with the latest official release 4.5.1 and the current master branch. The code maintainer cannot reproduce this for 4.5.2-beta1. In his reply the maintainer explains that "[i]n that case, this is a duplicate that was fixed in 4.5.2."
A vulnerability was found in appneta tcpreplay up to 4.4.4. It has been classified as problematic. This affects the function getlayer4v6 of the file /tcpreplay/src/common/get.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The identifier VDB-258333 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
