https://notcve.org/view.php?id=CVE-2023-2906
Due to a failure in validating the length provided by an attacker-crafted CP2179 packet, Wireshark versions 2.0.0 through 4.0.7 is susceptible to a divide by zero allowing for a denial of service attack. Debido a un error al validar la longitud proporcionada por un paquete CP2179 creado por un atacante, las versiones de Wireshark 2.0.0 a 4.0.7 son susceptibles a una división por cero, lo que permite un ataque de denegación de servicio. • https://gitlab.com/wireshark/wireshark/-/issues/19229 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6HCUPLDY7HLPO46PHMGIJSUBJFTT237C https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L4AVRUYSHDNEAJILVSGY5W6MPOMG2YRF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/TRKHFQPWFU7F3OXTL6IEIQSJG6FVXZTZ https://takeonme.org/cves/CVE-2023-2906.html • CWE-369: Divide By Zero •

In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement. En Wireshark versiones hasta 3.2.7, el Facebook Zero Protocol (también se conoce como FBZERO), podría entrar en un bucle infinito. Esto fue abordado en el archivo epan/dissectors/packet-fbzero.c corrigiendo la implementación del avance de compensación • https://gitlab.com/wireshark/wireshark/-/commit/3ff940652962c099b73ae3233322b8697b0d10ab https://gitlab.com/wireshark/wireshark/-/issues/16887 https://gitlab.com/wireshark/wireshark/-/merge_requests/467 https://gitlab.com/wireshark/wireshark/-/merge_requests/471 https://gitlab.com/wireshark/wireshark/-/merge_requests/472 https://gitlab.com/wireshark/wireshark/-/merge_requests/473 https://lists.debian.org/debian-lts-announce/2021/02/msg00008.html https://lists.fedoraproject.org/archives&#x • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the MIME Multipart dissector could crash. This was addressed in epan/dissectors/packet-multipart.c by correcting the deallocation of invalid MIME parts. En Wireshark versiones 3.2.0 hasta 3.2.6, versiones 3.0.0 hasta 3.0.13 y versiones 2.6.0 hasta 2.6.20, el disector MIME Multipart podría bloquearse. Esto fue abordado en el archivo epan/disactors/packet-multipart.c corrigiendo la desasignación de partes MIME no válidas • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00038.html https://gitlab.com/wireshark/wireshark/-/commit/5803c7b87b3414cdb8bf502af50bb406ca774482 https://gitlab.com/wireshark/wireshark/-/issues/16741 https://lists.debian.org/debian-lts-announce/2021/02/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4DQHPKZFQ7W3X34RYN3FWFYCFJD4FXJW https://lists.fedoraproject.org/archives&# •
