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 through 2.6.2, the create_app_running_mutex function in wsutil/file_util.c calls SetSecurityDescriptorDacl to set a NULL DACL, which allows attackers to modify the access control arbitrarily. En Wireshark hasta la versión 2.6.2, la función create_app_running_mutex en wsutil/file_util.c llama a SetSecurityDescriptorDacl para establecer un DACL NULL que permite que los atacantes modifiquen el control de acceso de forma arbitraria. • http://www.securityfocus.com/bid/104876 https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=14921 • CWE-20: Improper Input Validation •

The netmonrec_comment_destroy function in wiretap/netmon.c in Wireshark through 2.4.4 performs a free operation on an uninitialized memory address, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact. La función netmonrec_comment_destroy en wiretap/netmon.c en Wireshark, hasta la versión 2.4.4, realiza una operación de liberación en una dirección de memoria no inicializada, lo que permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) u otro tipo de impacto sin especificar. • https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=14397 https://code.wireshark.org/review/#/c/25660 https://code.wireshark.org/review/#/c/25660/2/wiretap/netmon.c https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=28960d79cca262ac6b974f339697b299a1e28fef • CWE-763: Release of Invalid Pointer or Reference •

In Wireshark before 2.2.12, the MRDISC dissector misuses a NULL pointer and crashes. This was addressed in epan/dissectors/packet-mrdisc.c by validating an IPv4 address. This vulnerability is similar to CVE-2017-9343. En Wireshark, en versiones anteriores a la 2.2.12, el disector MRDISC emplea de forma incorrecta un puntero NULL y se cierra inesperadamente. Esto se trató en epan/dissectors/packet-mrdisc.c validando la longitud de una dirección IPv4. • https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=14299 https://code.wireshark.org/review/#/c/25063 https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=80a695869c9aef2fb473d9361da068022be7cb50 https://lists.debian.org/debian-lts-announce/2019/01/msg00010.html https://www.wireshark.org/security/wnpa-sec-2018-02.html • CWE-476: NULL Pointer Dereference •
