A GC-Friendly Go Interning Cache

Ive seen a little gem pass by in a Go cryptography code review and I want to share it because I think its a pattern that can be reused. Lets start with a problem statement: crypto/x509 Certificate values take a bunch of memory, and for every open TLS connection you end up with a copy of the leaf...

OpenSSL: X.509 Email Address Variable Length Buffer Overflow

A stack-based buffer overflow was found in the way OpenSSL processes X.509 certificates with a specially crafted email address field. This issue could cause a server or a client application compiled with OpenSSL to crash or possibly execute remote code when trying to process the malicious...

USN-5710-1 openssl vulnerabilities

It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler...

UBUNTU-CVE-2022-3786

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate...

Vulnerabilities fixed in OpenSSL

Vulnerabilities have been fixed in OpenSSL 3. OpenSSL is widely found on web and mail servers but is also used by other types of systems. Think of network devices, embedded systems and containerized images. The vulnerabilities can be exploited by a malicious party to execute arbitrary code or cau...

PT-2022-5306

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.0.0 through 3.0.6 Description A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. This occurs after certificate chain signature verification and requires either a CA...

The vulnerability of the library function for working with X.509 certificates, LibKSBA, is related to a numerical overflow in the syntax analyzer CRL. This allows an attacker to execute any code in the target system.

The vulnerability of the library’s certificate handling function for X.509 certificates is related to a numerical overflow in the CRL syntax analyzer. Exploiting this vulnerability allows an attacker to send specially crafted data to the application, trigger a numerical overflow, and execute...
