MediaArea MediaInfoLib LXF element parsing heap-based buffer overflow vulnerability

Summary A heap-based buffer overflow vulnerability exists in the LXF element parsing functionality of MediaInfoLib versions: 26.01. A specially crafted .lxf file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. Confirmed Vulnerable...

CVE-2026-32739

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could exploit this vulnerability by providing a specially crafted HEIF High Efficiency Image File Format sequence file. This would trigger an infinite loop during file parsing, consuming 100% CPU...

CVE-2026-32740

A flaw was found in libheif, a library for decoding and encoding HEIF and AVIF image files. This heap-buffer-overflow vulnerability allows a remote attacker to write arbitrary data beyond the intended memory boundary. By crafting a malicious HEIF/AVIF file with a specific grid tile configuration,...

CVE-2026-32814

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. When processing a specially crafted HEIF or AVIF image containing a corrupted grid tile, the library fails to properly initialize memory. This can lead to an information disclosure, where uninitialized heap memory,...

CVE-2026-32741

A flaw was found in libheif, a library for decoding and encoding HEIF High Efficiency Image File Format and AVIF files. A remote attacker could exploit a heap buffer overflow vulnerability in the MaskImageCodec::decodemaskimage function by providing a specially crafted HEIF file containing a mask...

UBUNTU-CVE-2026-32740

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap-buffer-overflow write vulnerability in the grid tile compositing, allowing an attacker to write 64 bytes of fully attacker-controlled data past the end of a chroma plane heap allocation by craftin...

GHSA-2MGW-7Q6P-8GRG FPDI: Memory Exhaustion and Endless Loop in FPDI leads to Denial of Service

Impact This is a significant Denial of Service DoS vulnerability. Any application that uses FPDI to process user-supplied PDF files is at risk. An attacker can upload a small, malicious PDF file that will cause the server-side script to crash due to memory exhaustion or a script time-out. Repeate...

OpenMcdf: Uncatchable infinite loop in DirectoryTree.TryGetDirectoryEntry on crafted CFB directory cycle

Summary The BST name-lookup loop in DirectoryTree.TryGetDirectoryEntry OpenMcdf/DirectoryTree.cs:35-46 walks directory entries by repeatedly calling directories.TryGetSiblingchild, siblingType, validateColor. A crafted CFB file with cyclic Left/Right sibling links among directory entries -...

CVE-2026-32814 libheif: Uninitialized Heap Memory Information Leak via Failed Grid Tiles

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...

DEBIAN-CVE-2026-32738

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc box causes an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, mapping all samples to an empty...

gstreamer-plugins-ugly: GStreamer: Arbitrary code execution via ASF file processing

A flaw was found in GStreamer. This heap-based buffer overflow vulnerability in the ASF Demuxer component allows a remote attacker to execute arbitrary code. The issue arises from insufficient validation of user-supplied data length when processing stream headers within ASF Advanced Systems Forma...

Github Actions issued GITHUB_TOKEN disclosure in GitHub Actions logs

Summary Composer leaks the full contents of tokens configured as GitHub OAuth tokens if they do not match Composer's expected format for such tokens to stderr. GitHub has introduced a new format for GitHub Actions GITHUBTOKEN values. These tokens are validated in the same way by Composer on GitHu...

luksmeta: Data corruption when handling LUKS1 partitions with luksmeta

A data corruption vulnerability has been identified in the luksmeta utility when used with the LUKS1 disk encryption format. An attacker with the necessary permissions can exploit this flaw by writing a large amount of metadata to an encrypted device. The utility fails to correctly validate the...

freerdp: FreeRDP: Denial of Service via use-after-free in AUDIN format renegotiation

A use after free flaw was found in FreeRDP. AUDIN format renegotiation frees the active format list while the capture thread continues using audin-format, leading to a use after free in audioformatcompatible. A malicious server can trigger a client‑side heap use after free causing a crash...
