openssl: heap buffer overflow in CMS key unwrapping

A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...

httpd: Apache HTTP Server: Heap-based Buffer Overflow via untrusted content in mod_xml2enc

A flaw was found in Apache HTTP Server, specifically within the modxml2enc module. This heap-based buffer overflow vulnerability can be triggered when processing untrusted content through the xml2StartParse function. A remote attacker could potentially exploit this to cause a denial of service,...

httpd: Apache HTTP Server: Heap-based Buffer Overflow via malicious backend servers

A flaw was found in Apache HTTP Server. This heap-based buffer overflow vulnerability can be exploited by a malicious backend server when using ProxyPassReverseCookie directives. This could lead to a denial of service DoS condition, making the server unavailable to legitimate users...

CVE-2026-90682 Matthias-Wandel jhead WebP EXIF gpsinfo.c ProcessGpsInfo heap-based overflow

A security vulnerability has been detected in Matthias-Wandel jhead up to 3.3. This impacts the function ProcessGpsInfo of the file gpsinfo.c of the component WebP EXIF Handler. Such manipulation of the argument TAGGPSLAT/TAGGPSLONG leads to heap-based buffer overflow. An attack has to be...
