ALPINE-CVE-2026-33846

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

CVE-2026-40685

In Exim before 4.99.2, when JSON lookup is enabled, an out-of-bounds heap write can occur when a JSON operator encounters malformed JSON in an untrusted header, because of an incorrect implementation of \ skipping...

libtiff: libtiff: Arbitrary code execution or denial of service via signed integer overflow in TIFF file processing

A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations,...

CVE-2026-42512

CVE-2026-42512 is a remote-out-of-bounds write vulnerability in the FreeBSD dhclient environment construction. The bug arises when dhclient resizes the array of environment string pointers passed to dhclient-script; the memory allocation size is incorrectly calculated, leading to a heap buffer ov...

CVE-2026-42512 Remotely triggerable out-of-bounds heap write in dhclient

As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to...
