CVE-2026-68768

hashcat contains a heap-based buffer overflow out-of-bounds write in the outfilewrite function in src/outfile.c. When assembling output into a fixed-size buffer HCBUFSIZLARGE, 16 MB, the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that...

CVE-2026-68768

hashcat through 7.1.2 is affected by a heap buffer overflow in the outfile_write() function (src/outfile.c). When assembling output into a fixed-size buffer (~16 MB), the function appends the username, separator, hash, and plaintext via memcpy without validating that the accumulated length stays ...

EUVD-2026-64273

luci-lib-px5g LuCI contains a heap-based buffer overflow in the native ASN.1 encoding routine asn1addobj x509write.c when signing a certificate with a 2040-bit RSA key. For a 255-byte signature, the BIT STRING allocation is computed from the DER length encoding of 255 bytes, but the payload writt...

CVE-2026-62381

luci-lib-px5g (LuCI) in OpenWrt contains a heap-based buffer overflow in the ASN.1 encoding routine asn1_add_obj (x509write.c) triggered when signing a certificate with a 2040-bit RSA key . The BIT STRING allocation is sized for a 255-byte signature's DER length encoding, but prepending the unuse...

apr-util: Apache Portable Runtime Utility: Heap buffer overflow in APR memcached client

A flaw was found in the memcached client in the Apache Portable Runtime Utility apr-util. A remote, unauthenticated attacker can cause the application to crash or become unresponsive by sending a specially crafted response from a malicious or compromised memcached server, resulting in a denial of...

apr-util: Apache Portable Runtime Utility: Heap buffer overflow in redis client

A flaw was found in the Redis client in the Apache Portable Runtime Utility apr-util. A heap buffer overflow can be triggered when the application processes a specially crafted response from a Redis server, resulting in a crash and denial of service...

CVE-2026-18307

A flaw was found in GIMP. This heap-based buffer overflow vulnerability in the TIF file parsing component allows a remote attacker to execute arbitrary code.
