CVE-2026-119235

Unbounded Memory Allocation in Proxygen QPACK Decoder Leading to Denial of Service

proxygen's QPACK decoder enforced its size limit on a string literal in an encoder-stream instruction only after the entire literal had been received. A remote, unauthenticated HTTP/3 peer could send an insert instruction on the QPACK encoder stream that declares an arbitrarily large literal and then keep sending data, causing the decoder to buffer it without bound for the lifetime of the connection and exhaust memory, leading to denial of service. The issue occurs regardless of the advertised QPACK dynamic table capacity, including when the dynamic table is disabled. This issue affects proxygen versions prior to v2026.11.09.00.

CVE-2026-119236

Denial of Service via Unbounded Memory Growth in Facebook’s MVFST QUIC Server

An mvfst QUIC server retained CRYPTO frame data received at an encryption level (Initial or Handshake) that the TLS handshake had already moved past. Because the transport treated this data as delivered, it did not count against the CRYPTO stream buffer limit. A remote, unauthenticated client could complete a handshake, withhold its acknowledgment of the server's HANDSHAKE_DONE frame so that Handshake keys stay in use, and keep sending Handshake-level CRYPTO data at increasing offsets, causing unbounded memory growth on the server and leading to denial of service. This issue affects mvfst versions prior to v2026.11.09.00.

HHVM Denial of Service via Malformed Request Parameters

When parsing request variables such as query-string and form parameters, HHVM did not check that appending a nested array succeeded before descending into it. A remote, unauthenticated attacker could send a GET or POST request which would crash the HHVM server process before any application code runs, leading to denial of service. This issue affected HHVM prior to 23c061f4e804a51badd5f85227e65185651253b5.

Directory Traversal in dpkg Source Package Unpacking

A directory traversal bug was discovered when unpacking 3.0 (quilt) source packages, where the packaging tarball could contain the quilt database directory (.pc) with attacker controlled symlinks, where that in combination with patches that would fail to apply, could be used to make the code used to restore the backup files to either modify or remove the files pointed to by the attacker controlled symlinks.
