CVE-2026-84444 libheif uncompressed tiled image encoding allows out-of-bounds write

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, when WITHUNCOMPRESSEDCODEC is enabled, heifcontextaddimagetile accepts an independently constructed tile whose component-plane dimensions do not match the tile geometry established by the prototype image...

unbound: Unbound: Denial of Service via use-after-free in DoQ stream output buffer

A flaw was found in Unbound. This vulnerability occurs in the DNS-over-QUIC DoQ stream output buffer when a client sends a RESETSTREAM, causing the output buffer to be freed while retransmission entries still point to it. A remote attacker, by querying Unbound over DoQ, withholding acknowledgment...

CVE-2026-78227

NLnet Labs Unbound versions 1.22.0 through 1.26.1 contain a use-after-free vulnerability in the DNS-over-QUIC (DoQ) implementation, triggered only when compiled with '--with-libngtcp2'. The root cause is that ngtcp2's retransmission buffer retains a shallow pointer into a per-stream output buffer...

CVE-2026-78227 Use-after-free in DoQ stream output buffer on reset re-transmission

NLnet Labs Unbound 1.22.0 up to and including 1.26.1, has a use-after-free vulnerability when compiled for DNS-over-QUIC support with '--with-libngtcp2'. Each DoQ stream owns an output buffer that holds the DNS response. ngtcp2's retransmission buffer keeps a shallow pointer into the output buffe...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. In versions starting from 2.6 and prior to 7.4.3, an unauthenticated client can cause the output buffer to grow indefinitely, until the server runs out of memory or is terminated. By default, Redis’s configuration does not...

CVE-2026-58081

A flaw was found in iconv. Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly validate the size of the provided output buffer before writing converted characters. This oversight could allow an application using iconv to convert untrusted input with one of the affected...
