OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to denial of service from unserialized data access because remote attackers can make a series of VOTE_Debug RPC calls to crash a database server within the SVOTE_Debug RPC handler. OpenAFS versiones anteriores a 1.6.24 y versiones 1.8.x anteriores a 1.8.5, es propenso a una denegación de servicio por acceso a datos no serializados porque los atacantes remotos pueden llevar a cabo una serie de llamadas RPC de VOTE_Debug para bloquear un servidor de base de datos dentro del manejador RPC de SVOTE_Debug. • https://lists.debian.org/debian-lts-announce/2019/11/msg00002.html https://openafs.org/pages/security/OPENAFS-SA-2019-003.txt • CWE-502: Deserialization of Untrusted Data •

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several data types used as RPC input variables were implemented as unbounded array types, limited only by the inherent 32-bit length field to 4 GB. An unauthenticated attacker could send, or claim to send, large input values and consume server resources waiting for those inputs, denying service to other valid connections. Se ha descubierto un problema en OpenAFS, en versiones anteriores a la 1.6.23 y versiones 1.8.x anteriores a la 1.8.2. Se implementaron varios tipos de datos empleados como variables de entrada RPC como tipos de array sin limitar, limitados solo por el campo length de 32 bits a 4 GB. • http://openafs.org/pages/security/OPENAFS-SA-2018-003.txt http://www.securityfocus.com/bid/106375 https://lists.debian.org/debian-lts-announce/2018/09/msg00024.html https://www.debian.org/security/2018/dsa-4302 • CWE-400: Uncontrolled Resource Consumption •

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several RPC server routines did not fully initialize their output variables before returning, leaking memory contents from both the stack and the heap. Because the OpenAFS cache manager functions as an Rx server for the AFSCB service, clients are also susceptible to information leakage. For example, RXAFSCB_TellMeAboutYourself leaks kernel memory and KAM_ListEntry leaks kaserver memory. Se ha descubierto un problema en OpenAFS, en versiones anteriores a la 1.6.23 y versiones 1.8.x anteriores a la 1.8.2. • http://openafs.org/pages/security/OPENAFS-SA-2018-002.txt https://lists.debian.org/debian-lts-announce/2018/09/msg00024.html https://www.debian.org/security/2018/dsa-4302 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. The backup tape controller (butc) process accepts incoming RPCs but does not require (or allow for) authentication of those RPCs. Handling those RPCs results in operations being performed with administrator credentials, including dumping/restoring volume contents and manipulating the backup database. For example, an unauthenticated attacker can replace any volume's content with arbitrary data.

OpenAFS 1.x before 1.6.22 does not properly validate Rx ack packets, which allows remote attackers to cause a denial of service (system crash or application crash) via crafted fields, as demonstrated by an integer underflow and assertion failure for a small MTU value. OpenAFS en versiones 1.x anteriores a la 1.6.22 no valida paquetes Rx ack correctamente, lo que permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado del sistema o de la aplicación) mediante campos manipulados, tal y como demuestra un subdesbordamiento de enteros y fallo de aserción para un valor MTU pequeño. • https://bugs.debian.org/883602 https://lists.debian.org/debian-lts-announce/2017/12/msg00016.html https://www.debian.org/security/2017/dsa-4067 https://www.openafs.org/pages/security/OPENAFS-SA-2017-001.txt • CWE-617: Reachable Assertion •
