CVE-2026-34182

Issue Summary: Cryptographic Message Services CMS processing fails to perform sufficient input validation on the cipher and tag length fields of AuthEnvelopedData containers, leading to various potential compromises. Impact Summary: Attackers making use of these vulnerabilities may achieve...

CVE-2026-34180

Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive element whose content exceeds 2 gigabytes in length may cause a heap buffer over-read on 64-bit Unix and Unix-like platforms. Impact summary: The heap buffer over-read may crash the application Denial of Service or to...

CVE-2026-9076

Issue summary: When CMS password-based decryption RFC 3211 / PWRI key unwrap processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in kekunwrapkey. Impact summary: A heap buffer over-read may trigger a crash which leads to Denial of...

CVE-2026-7383 Possible Heap Buffer Overflow in ASN.1 Multibyte String Conversion

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1mbstringncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In...

CVE-2026-7383

OpenSSL is vulnerable to a signed integer overflow when sizing the destination buffer for Unicode output in ASN1_mbstring_ncopy() . This occurs because the destination size for BMPSTRING (UTF-16), UNIVERSALSTRING (UTF-32), and UTF8STRING is computed using signed integers, which can overflow when ...

EulerOS 2.0 SP11 : openssl (EulerOS-SA-2026-2258)

According to the versions of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : Issue summary: When a delta CRL that contains a Delta CRL Indicator extension is processed a NULL pointer dereference might happen if the require...

CVE-2026-42771: Out-of-bounds Read

Issue summary: When the X509VERIFYPARAMset1email is called by an application to validate a crafted e-mail address, such as during S/MIME message validation, an out of bounds read can happen. Impact summary: This out of bounds read will not directly exfiltrate the data read to the attacker so the...

CVE-2026-35188: Double Free

Issue summary: A malicious server can exploit TLS OCSP stapling by delivering a crafted response through the statusrequest extension, triggering a double-free in the client's certificate verification path. Impact summary: Successful exploitation allows an attacker to corrupt heap memory via a...

PT-2026-47837

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description A NULL pointer dereference can occur in a CMP client application when processing a crafted CMP response. An attacker controlling a CMP server or acting as a man-in-the-middle can send a CRMF...

CVE-2026-34181: Improper Validation of Integrity Check Value

Issue Summary: The PKCS12 file processing fails to perform sufficient input validation for files that use Password-Based Message Authentication Code 1 PBMAC1 integrity mechanism allowing a certificate and private key forgery. Impact Summary: An attacker impersonating a user can cause a service...
