httpd: httpd: HTTP/2 Remote Denial of Service via compression bomb and Slowloris-style attack

A flaw was found in HTTP/2, affecting various web servers. A remote attacker can exploit this vulnerability by combining an HPACK compression bomb with a zero-byte flow-control window. This technique allows a small amount of data to expand into large memory allocations on the server, which are th...

BIT-ENVOY-2026-47774 Envoy vulnerable to HTTP/2 memory exhaustion via cookie header size bypass and HPACK amplification

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability in Envoy's HTTP/2 downstream request processing allows an unauthenticated remote client to trigger excessive memory consumption, potentiall...

Amazon Linux 2023 : ecs-service-connect-agent (ALAS2023-2026-1893)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1893 advisory. A denial-of-service vulnerability was found in Envoy's HTTP/2 HPACK header compression implementation. A remote attacker could send a specially crafted HTTP/2 request that triggers disproportionately...

Amazon Linux 2023 : ImageMagick, ImageMagick-c++, ImageMagick-c++-devel (ALAS2023-2026-1826)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1826 advisory. When writing an IPTC output file a malicious input file could cause an out of bounds read of a single byte. as per:...

Amazon Linux 2 : ecs-service-connect-agent, --advisory ALAS2ECS-2026-126 (ALASECS-2026-126)

The version of ecs-service-connect-agent installed on the remote host is prior to v1.34.13.2-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2026-126 advisory. A denial-of-service vulnerability was found in Envoy's HTTP/2 HPACK header compression implementation. A...

CVE-2026-49271 libheif: Wrapped icef compressed-unit range check causes out-of-bounds read in uncompressed HEIF decoder

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...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...
