OpenSSL 3.0.0 < 3.0.19 Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 3.0.19. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.0.19 advisory. - Issue summary: A type confusion vulnerability exists in the signature verification of signed PKCS7 data where an ASN1TYPE union...

RHEL 9 : openssl (RHSA-2026:1349)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:1349 advisory. OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength...

UBUNTU-CVE-2025-66199

Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of up to approximately 22 MiB and...

The x509 application adds trusted use instead of rejected use

Issue summary: Use of -addreject option with the openssl x509 application adds a trusted use instead of a rejected use for a certificate. Impact summary: If a user intends to make a trusted certificate rejected for a particular use it will be instead marked as trusted for that use. A copy & paste...

UBUNTU-CVE-2025-69420

Issue summary: A type confusion vulnerability exists in the TimeStamp Response verification code where an ASN1TYPE union member is accessed without first validating the type, causing an invalid or NULL pointer dereference when processing a malformed TimeStamp Response file. Impact summary: An...

Linux Distros Unpatched Vulnerability : CVE-2025-69418

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Issue summary: When using the low-level OCB API directly with AES-NI orother hardware-accelerated code paths, inputs whose length is not a multipleof 16 bytes c...

Linux Distros Unpatched Vulnerability : CVE-2025-15467

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Issue summary: Parsing CMS AuthEnvelopedData or EnvelopedData message with maliciously crafted AEAD parameters can trigger a stack buffer overflow. Impact...

UBUNTU-CVE-2025-68160

Issue summary: Writing large, newline-free data into a BIO chain using the line-buffering filter where the next BIO performs short writes can trigger a heap-based out-of-bounds write. Impact summary: This out-of-bounds write can cause memory corruption which typically results in a crash, leading ...

OpenSSL 1.0.2 < 1.0.2zn Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2zn. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2zn advisory. - Issue summary: A type confusion vulnerability exists in the signature verification of signed PKCS7 data where an ASN1TYPE union...
