CVE-2026-47178 libheif has Heap Out Of Bounds Write in unci subsystem

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.19.0 through 1.21.2, a crafted HEIF file uncompressed unci codec, tiled, component-interleaved, 4:2:0 triggers a heap out-of-bounds write in libheif's uncompressed tile decoder. The write overwrites the C++ vtable pointer o...

CVE-2026-47178 libheif has Heap Out Of Bounds Write in unci subsystem

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.19.0 through 1.21.2, a crafted HEIF file uncompressed unci codec, tiled, component-interleaved, 4:2:0 triggers a heap out-of-bounds write in libheif's uncompressed tile decoder. The write overwrites the C++ vtable pointer o...

CVE-2026-47178

CVE-2026-47178 affects libheif up to v1.21.2, where a crafted uncompressed HEIF image (unci codec, tiled, component-interleaved, 4:2:0) can trigger a heap out-of-bounds write in the uncompressed tile decoder. The write overwrites a nearby C++ vtable pointer, causing the next virtual call to dispa...

EUVD-2026-46428

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.19, decodercontext::decodesliceunittiles libde265/decctx.cc:920 reads pps.CtbAddrRStoTSctbAddrRS at line 966 where ctbAddrRS = ctbY ctbsWidth + ctbX is computed from PPS-supplied colBd/rowBd arrays without...

pyasn1: Quadratic complexity in OBJECT IDENTIFIER and RELATIVE-OID processing allows denial of service

Impact The BER/CER/DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs. A small crafted payload tens of kilobytes containing an OID with many arcs consumes seconds of CPU per decode call, allowing denial of service in any application tha...

pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...

GHSA-M4P7-R5RC-7G4J pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...

openssl: OpenSSL: Heap buffer over-read in ASN.1 decoding can lead to denial of service or information disclosure.

A flaw was found in OpenSSL. An integer truncation vulnerability in the ASN.1 decoder can occur when processing a crafted DER-encoded ASN.1 structure with a primitive element exceeding 2 gigabytes. A remote attacker could exploit this to cause a heap buffer over-read. This may lead to an...

SUSE CVE-2026-55831

Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, Netty's SPDY SETTINGS decoder accepts a peer-declared SETTINGS entry count up to the 24-bit frame-length limit and materializes every unique setting ID in...

CVE-2026-63855

A flaw was found in the Linux kernel's AMDGPU Video Core Next VCN driver. The VCN encoder and decoder rings do not support 64-bit user fence writes. A local attacker could exploit this by submitting commands with unsupported 64-bit user fences, which could lead to system instability or a denial o...
