Description

New point version

This update has a security fix:

OpenSSL Security Advisory [3rd September 2024]
==============================================

Possible denial of service in X.509 name checks (CVE-2024-6119)
===============================================================

Severity: Moderate

Issue summary: Applications performing certificate name checks (e.g., TLS
clients checking server certificates) may attempt to read an invalid memory
address resulting in abnormal termination of the application process.

Impact summary: Abnormal termination of an application can a cause a denial of
service.

Applications performing certificate name checks (e.g., TLS clients checking
server certificates) may attempt to read an invalid memory address when
comparing the expected name with an `otherName` subject alternative name of an
X.509 certificate. This may result in an exception that terminates the
application program.

Note that basic certificate chain validation (signatures, dates, ...) is not
affected, the denial of service can occur only when the application also
specifies an expected DNS name, Email address or IP address.

TLS servers rarely solicit client certificates, and even when they do, they
generally don't perform a name check against a "reference identifier" (expected
identity), but rather extract the presented identity after checking the
certificate chain.  So TLS servers are generally not affected and the severity
of the issue is Moderate.

The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
OpenSSL 1.1.1 and 1.0.2 are also not affected by this issue.

OpenSSL 3.3, 3.2, 3.1 and 3.0 are vulnerable to this issue.

OpenSSL 3.3 users should upgrade to OpenSSL 3.3.2

OpenSSL 3.2 users should upgrade to OpenSSL 3.2.3

OpenSSL 3.1 users should upgrade to OpenSSL 3.1.7

OpenSSL 3.0 users should upgrade to OpenSSL 3.0.15

This issue was reported on 16th June 2024 by David Benjamin (Google),
reiterating an AddressSanitizer issue raised on 30th September 2021.  The fix
was developed by Viktor Dukhovni.
