curl: libcurl: Integer truncation in curl_easy_ssls_import() causes TLS sessions to never expire

Summary: curleasysslsimport deserializes a TLS session blob and stores it in the in-memory session cache. In Curlsslsessionunpack lib/vtls/vtlsspack.c:311, the validuntil field is read as uint64t and cast directly to curlofft int64t with no bounds check — so a crafted blob encoding validuntil =...

libpng: libpng: Information disclosure and denial of service via integer truncation in simplified write API

A flaw was found in libpng, a reference library for PNG Portable Network Graphics raster image files. An integer truncation vulnerability exists in the pngwriteimage16bit and pngwriteimage8bit simplified write API functions. A local attacker could exploit this flaw by providing a negative row...

AZL-82961 CVE-2026-35199 affecting package SymCrypt 103.8.0-1

SymCrypt is the core cryptographic function library currently used by Windows. From 103.5.0 to before 103.11.0, The SymCryptXmssSign function passes a 64-bit leaf count value to a helper function that accepts a 32-bit parameter. For XMSS^MT parameter sets with total tree height = 32 which include...

CVE-2026-23457

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntracksip module. This vulnerability arises from an integer truncation error when processing the Content-Length header in Session Initiation Protocol SIP messages. On 64-bit systems, large Content-Length valu...

CVE-2026-34610 leancrypto: Integer truncation in X.509 name parser enables certificate identity impersonation

The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms. Prior to version 1.7.1, lcx509extractnamesegment casts sizet vlen to uint8t when storing the Common Name CN length. An attacker who crafts a certificate with CN = victim's CN +...
