Vulnerabilidades

The TIFF decoder does not place a limit on the size of compressed tile data. A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height, and encoded size) to make the decoder decode large amounts of compressed data, consuming excessive memory and CPU.

A maliciously-crafted image can cause excessive CPU consumption in decoding. A tiled image with a height of 0 and a very large width can cause excessive CPU consumption, despite the image size (width * height) appearing to be zero.

Under some circumstances, this weakness allows a user who has access to run the “ps” utility on a machine, the ability to write almost unlimited amounts of unfiltered data into the process heap.

Se ha encontrado un fallo de desbordamiento de búfer en base/gdevdevn.c:1973 en devn_pcx_write_rle() en ghostscript. Este problema puede permitir a un atacante local provocar una denegación de servicio mediante la salida de un archivo PDF manipulado para un dispositivo DEVN con gs.

Se encontró una falla de use-after-free en el netfilter del kernel de Linux en la forma en que un usuario activa la función nft_pipapo_remove con el elemento, sin un NFT_SET_EXT_KEY_END. Este problema podría permitir que un usuario local bloquee el sistema o potencialmente aumente sus privilegios en el sistema.

Insufficient policy enforcement in Intents in Google Chrome on Android prior to 109.0.5414.119 allowed a remote attacker to bypass same origin policy via a crafted HTML page. (Chromium security severity: Medium)

Incorrect security UI in Notifications in Google Chrome on Android prior to 103.0.5060.53 allowed a remote attacker to obscure the full screen notification via a crafted HTML page. (Chromium security severity: Low)

Uninitialized Use in FFmpeg in Google Chrome prior to 108.0.5359.71 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)

Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. Certifi prior to version 2023.07.22 recognizes "e-Tugra" root certificates. e-Tugra's root certificates were subject to an investigation prompted by reporting of…

A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data to…

A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.

Se encontró una falla en Keylime. Debido a su naturaleza de bloqueo, el registrador de Keylime está sujeto a una denegación de servicio remota contra sus conexiones SSL. Esta falla permite a un atacante agotar todas las conexiones disponibles.

A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their…

A directory traversal problem in the URL decoder of librsvg before 2.56.3 could be used by local or remote attackers to disclose files (on the local filesystem outside of the expected area), as demonstrated by href=".?../../../../../../../../../../etc/passwd" in an xi:include element.

A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a…

A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request to view the information that is part…

A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of…

An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing…

An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length.…

La característica PKCS#11 en ssh-agent en OpenSSH anterior a 9.3p2 tiene una ruta de búsqueda insuficientemente confiable, lo que lleva a la ejecución remota de código si un agente se reenvía a un sistema controlado por un atacante. (El código en /usr/lib no es necesariamente seguro para cargar en ssh-agent). NOTA:…

A flaw was found in the keylime attestation verifier, which fails to flag a device's submitted TPM quote as faulty when the quote's signature does not validate for some reason. Instead, it will only emit an error in the log without flagging the device as untrusted.
