Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by submitting an oversized Base64-encoded password to the login handler in /bin/netis.cgi. Attackers can exploit the custom Base64 decoder's lack of output length validation against the fixed-size stack buffer to achieve remote cod…

NLTK versiones anteriores a 3.9.4 contienen una vulnerabilidad de recursión no acotada en JSONTaggedDecoder.decode_obj() que permite a atacantes causar denegación de servicio mediante estructuras JSON profundamente anidadas. Un payload malicioso que exceda el límite de recursión desencadena una excepción RecursionError no controlada que causa el fallo del proceso Python. Afecta aplicaciones de procesamiento de lenguaje natural en infraestructuras LATAM, incluyendo sistemas de análisis de datos y chatbots empresariales.

AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId() returns video_id_hash credentials for any video by encoder_queue_id without ownership verification, and useVideoHashOrLogin() converts this hash into passwordless login as the video owner. Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the v…

kin-openapi, biblioteca Go para procesar archivos OpenAPI, presenta una vulnerabilidad (CVSS 7.5) en versiones 0.10.0 a 0.141.0 que permite un acceso a memoria nula cuando procesa campos escalares malformados en solicitudes multipart/form-data. Un atacante puede causar bloqueo de servicio contra aplicaciones que usan esta biblioteca para validación de APIs. Empresas en LATAM con servicios REST y microservicios basados en Go están en riesgo si implementan kin-openapi sin parchear.

ICEcoder 8.1 contains an unauthenticated remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary OS commands by chaining an authentication bypass, CSRF validation bypass, and unsanitized command execution. Attackers can send a single HTTP POST request to the terminal endpoint with a password parameter to bypass authentication, a non-empty csrf parameter to sk…

jxl-oxide is a pure Rust implementation of a JPEG XL decoder. Prior to jxl-grid 0.6.2, decoding a crafted JPEG XL image on a 32-bit platform can overflow length calculations in AlignedGrid::with_alloc_tracker and related grid and subgrid arithmetic. A 65536 x 65536 frame can pass the frame-area limit while overflowing the usize element count, causing modular, VarDCT, or filter rendering paths to a…

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.0, a crafted HEIF sequence accepted by heif_context_read_from_memory() with the msf1 sequence brand can cause unbounded heap allocation. In libheif/sequences/seq_boxes.cc, Box_stsz::parse() applies max_sequence_frames only to variable-size samples, so fixed-size mode accepts an attacker-controlled sample_count witho…
