Descrição técnica

Monoceros versions before 0.30 for Perl allow a request declaring a large Content-Length to kill a worker by exhausting memory. The request body is read in a loop that asks sysread for all of the remaining declared length at once. Perl grows the read buffer to that size before any data arrives, so a length larger than available memory makes the worker exit with an uncatchable out of memory error before the application is called. A remote attacker can force a worker restart with each request of a few bytes.

——0FFmpeg 9.0 through 9.0.2 built with liblcevc_dec fails to validate LCEVC enhanced output dimensions against max_pixels in libavcodec/decode.c before frame allocation. Attackers can supply crafted H.264, HEVC or VVC streams declaring huge LCEVC resolutions to force oversized get_buffer2() allocations and exhaust memory.14h CVE-2026-1252265.5 MÉD

—

——0FFmpeg through 9.0.2 contains an uncontrolled memory allocation vulnerability in sbg_read_header() in libavformat/sbgdec.c that derives an unbounded default frame size from the script's sample rate. Attackers can supply a crafted SBaGen script declaring a very high -r sample rate so the wavesynth decoder allocates enormous audio frames, exhausting memory and causing denial of service.14h CVE-2026-1252075.5 MÉD

—

——0FFmpeg through 9.0.2 contains an uncontrolled memory allocation vulnerability in the Interplay ACM decoder that allows attackers to exhaust memory via an attacker-controlled block size. Attackers can supply a crafted ACM file with maximum level and row count in extradata, making decode_init() allocate nearly a gigabyte and deny service.14h CVE-2026-1251045.5 MÉD

—

——0FFmpeg through 9.0.2 contains a memory exhaustion vulnerability in ape_decode_frame() in libavcodec/apedec.c that fails to enforce the 73728-sample limit for legacy APE frames. Attackers can supply a crafted legacy Monkey's Audio file declaring an enormous nblocks value to force gigabyte-scale allocations and cause denial of service.14h CVE-2026-1236167.5 ALT

——12imgproxy from 3.3.0 before 4.0.16 contains an unbounded memory allocation vulnerability in the ICO loader that fails to validate the data_size field. Attackers can supply a crafted 23-byte ICO file declaring a ~4GB data_size to trigger memory exhaustion and worker crashes without authentication.2d CVE-2026-1235637.5 ALT

31.8%

——10Devalue before 5.9.3 contains a validation bypass vulnerability that allows custom ArrayBuffer revivers to skip typed-array allocation checks in the parse function. Attackers can supply very small crafted input processed by a malformed ArrayBuffer reviver to allocate massive ArrayBuffers, causing memory exhaustion and denial of service.2d
