CVE-2026-90473: Integer Overflow or Wraparound

msgpack-java through 0.9.12 contains an integer overflow vulnerability in MessageUnpacker.skipValue when processing MAP32 containers with large element counts. Attackers can supply a MAP32 element count at or above 0x40000000 that wraps when doubled, causing the parser cursor to desynchronize and...

CVE-2026-53600

A flaw was found in async-tar, a library for reading and writing tar archives in Rust. The library incorrectly applies a buffered PAX size extension to an intermediary extension header instead of the intended next file entry. This allows an attacker to craft a malicious tar archive that manipulat...

CVE-2026-49263

A flaw was found in Capstone, a disassembly framework, affecting its WebAssembly WASM backend. A remote attacker could exploit this by providing a specially crafted brtable instruction. This could lead to a denial of service, where the disassembler gets stuck in a loop, or cause parser...

haproxy: HAProxy: Response smuggling due to integer overflow in FastCGI record length handling

A flaw was found in HAProxy. A malicious FastCGI Fast Common Gateway Interface backend can exploit an integer overflow vulnerability in the fcgiconn structure's drl field. This occurs when specific contentLength and paddingLength values cause the drl field to wrap to zero, leading to incorrect...

CVE-2026-49263 Capstone WASM `br_table` instruction-size truncation can cause no-progress disassembly and parser desynchronization

Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's WebAssembly backend accepts attacker-controlled raw WASM instruction bytes through the public csdisasm and csdisasmiter APIs. For a large but well-formed brtable instruction, the WASM decoder accumulates the immediate...

gstreamer1-plugins-bad-free: GStreamer: Denial of service via AV1 tile_list_obu parser byte/bit confusion

A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The gstav1parserparsetilelistobu function passes a byte count to a bit-reader API that expects a bit count, causing parser desynchronization. A remote attacker could trick a user into opening a special...

CVE-2026-53655 node-tar applies PAX size override to intermediary GNU long-name/long-link headers, causing tar parser interpretation differential (file smuggling)

node-tar is a full-featured Tar for Node.js. Prior to 7.5.16, tar node-tar applies a PAX extended header's size= record and other PAX overrides to the next header entry of any type, including intermediary metadata headers such as a GNU long-name L or long-link K entry. Per POSIX pax, a PAX extend...

CVE-2026-53655

node-tar (node-tar) before version 7.5.16 is vulnerable: it applies a PAX extended header size override to the next header entry, including intermediary L/K/x headers, which desynchronizes the stream cursor from other tar implementations. This yields a tar-parser interpretation differential (CWE-...
