Security Bulletin: Multiple Vulnerabilities in cryptography bundled with IBM Fusion, IBM Fusion HCI, IBM Fusion Data Cataloging, and IBM Fusion Content-Aware Storage

Summary IBM Fusion, IBM Fusion HCI, IBM Fusion Data Cataloging, and IBM Fusion Content-Aware Storage include the cryptography library, which is vulnerable to a critical buffer overflow and an improper certificate validation flaw. A classic buffer overflow vulnerability exists when non-contiguous...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

CVE-2026-9265

Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in printattribute UTF8STRING path. printattribute copies a UTF8STRING ASN.1 attribute value into a heap buffer sized exactly to its declared length via strncpy, leaving no NUL terminator. Downstream callers run strlen on...

RLSA-2026:26275 Important: openssl security update

OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength general-purpose cryptography library. Security Fixes: openssl: Use After Free with SSLfreebuffers CVE-2024-4741 openssl: Heap Use-After-Free in OpenSSL...

SUSE CVE-2017-20240

Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks. These versions use Perl's built-in eq comparison. Discrepancies in timing could be used to guess the underlying derived-key...

CVE-2026-12200

A security vulnerability has been detected in Ritlabs TinyWeb Server up to 1.94 on Win32. This impacts an unknown function in the library libeay32.dll.html of the component Header Handler. The manipulation of the argument Authorization leads to stack-based buffer overflow. The attack can be...

CVE-2026-9638

Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography...

Security Fixes: openssl: OpenSSL: Heap buffer overflow due to signed integer overflow in Unicode output sizing CVE-2026-73...

CVE-2026-42767 NULL Pointer Dereference in CRMF EncryptedValue Decryption

Issue summary: An attacker-controlled CMP Certificate Management Protocol server could trigger a NULL pointer dereference in a CMP client application. Impact summary: A NULL pointer dereference causes a crash of the application and a Denial of Service. An attacker controlling a CMP server or acti...

cryptography: Cryptography: Buffer overflow via non-contiguous buffer in API

A flaw was found in the cryptography library. This vulnerability occurs when a non-contiguous buffer is passed to certain application programming interfaces APIs that accept Python buffers, such as Hash.update. A remote attacker could exploit this to cause a buffer overflow, potentially leading t...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
