CVE-2026-43994

Coturn is a free open source implementation of TURN and STUN Server. Versions prior to 4.10.0 contain a stack buffer overflow in decodeoauthtokengcm. A uint16t noncelen field read from an attacker-supplied OAuth access token 0-65535 is passed directly to memcpy as the copy length into a 256-byte...

CVE-2026-45696

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, the HTJ2K High-Throughput JPEG 2000 decoder, htundoimpl in OpenEXRCore is vulnerable to a heap-buffer-overflow READ. The htundoimp...

CVE-2026-44663

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, an integer overflow in htundoimpl in src/lib/OpenEXRCore/internalht.cpp leads to a heap-buffer overflow when decoding a crafted...

CVE-2026-45696

CVE-2026-45696 affects OpenEXR 3.4.0–3.4.11, where the HTJ2K decoder’s ht_undo_impl() can perform a heap-buffer-overflow READ due to a width mismatch between the EXR codestream and the declared line width. The decoder copies 32-bit samples from cur_line->i32[] without validating the OpenJPH li...

CVE-2026-44663 OpenEXR: Integer overflow in the HTJ2K decoder leads to heap-buffer-overflow

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, an integer overflow in htundoimpl in src/lib/OpenEXRCore/internalht.cpp leads to a heap-buffer overflow when decoding a crafted...

CVE-2026-44663

Technical summary (OpenEXR CVE-2026-44663): In OpenEXR 3.4.0–3.4.11, ht_undo_impl() in OpenEXRCore/internal_ht.cpp performs an integer overflow when computing bytes_per_element during HTJ2K decoding, causing a heap-buffer-overflow on large widths (e.g., >= 536,870,912 for FLOAT). The overflow ...

CVE-2026-48980

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or...

CVE-2026-48983

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, a symlink race condition exists in per-device and per-user pad directory creation. pamusb uses a check-then-act pattern: it calls lstat to test for existence and then calls mkdir separate...

CVE-2026-48982

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-48981

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, pamusb calls xmlReadFile with flags=0 when loading the configuration file, allowing libxml2 to process external entity references XXE, potentially making outbound network connections or...

CVE-2026-43915

Coturn is a free open source implementation of TURN and STUN Server. Versions prior to 4.11.0 contain a stored cross-site scripting XSS vulnerability in the web-admin HTTPS interface. An attacker who can create a TURN allocation with a crafted USERNAME value can inject HTML/JavaScript that execut...

CVE-2026-52726

A flaw was found in Dulwich, a pure-Python implementation of Git file formats and protocols. This vulnerability allows a remote attacker to achieve arbitrary code execution by crafting a malicious Git submodule. When a user clones or updates a repository with such a submodule, the...
