CVE-2026-49271

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unitoffset + unitsize. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector...

CVE-2026-56211

A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder's SVC Scalable Video Coding layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer contex...

CVE-2026-56208

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...

CVE-2026-56209 Libaom: libaom: arbitrary address write via svc layer context oob and cyclic refresh map pointer hijack

An arbitrary address write vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC Scalable Video Coding layer ID control function allows an attacker to inject an arbitrary pointer into the cyclic refresh map field via crafted image pixel value...

CVE-2026-56208

CVE-2026-56208 affects libaom, the reference AV1 codec. A flaw in the encoder’s Look-Ahead Processing (LAP) mode bypasses the first-pass stats ring-buffer guard when g_lag_in_frames is 1 or more, causing a 232-byte out-of-bounds write on every frame after the second. This can corrupt heap objects...

Astra Linux – Vulnerability in Netty

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.129.Final and 4.2.8.Final, the io.netty.handler.codec.http.HttpRequestEncoder had a CRLF injection in the request URI during request construction. This led to request smuggling when HttpRequestEncoder w...
