CVE-2026-61870

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the VIFF encoder when memory allocation fails. Attackers can trigger allocation failures by processing specially crafted VIFF images to exhaust available memory and cause denial of service...

CVE-2026-61861

ImageMagick before 7.1.2-26 contains a use-after-free vulnerability in the FormatMagickCaption method when memory allocation fails. Attackers can trigger memory allocation failures to cause a dangling pointer to reference freed memory, potentially enabling denial of service or code execution...

CVE-2026-61465

ImageMagick before 7.1.2-26 and 6.9.13-51 lacks a check for the allowed memory allocation limit in matrix-backed operations (e.g., -canny). A crafted image can cause ImageMagick to allocate more memory than policy permits, resulting in a denial of service. Affected components: ImageMagick's memor...

CVE-2026-61465

ImageMagick before 7.1.2-26 and 6.9.13-51 is missing a check for the allowed memory allocation limit in matrix-backed operations such as -canny. An attacker can supply a crafted image that causes ImageMagick to allocate more memory than permitted by the configured policy, resulting in a denial of...

github.com/quic-go/quic-go: quic-go: Denial of Service via excessive memory allocation in HTTP/3 trailers

A flaw was found in quic-go, an implementation of the QUIC protocol in Go. A remote attacker can exploit this by sending specially crafted HTTP/3 trailer fields. This can cause the system to allocate excessive memory, leading to a denial-of-service DoS condition where the affected server or clien...

wasmtime: Wasmtime: Denial of Service via large WebAssembly table allocation

A flaw was found in Wasmtime, a runtime for WebAssembly. A remote attacker could exploit an arithmetic overflow vulnerability by instantiating a WebAssembly module or component that attempts to allocate an extremely large table using the WebAssembly memory64 proposal. This flaw causes Wasmtime to...
