"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-721 advisory.
Issue summary: Applications performing certificate name checks (e.g., TLSclients checking server
certificates) may attempt to read an invalid memoryaddress resulting in abnormal termination of the
application process.
Impact summary: Abnormal termination of an application can a cause a denial ofservice.
Applications performing certificate name checks (e.g., TLS clients checkingserver certificates) may
attempt to read an invalid memory address whencomparing the expected name with an `otherName` subject
alternative name of anX.509 certificate. This may result in an exception that terminates theapplication
program.
Note that basic certificate chain validation (signatures, dates, ...) is notaffected, the denial of
service can occur only when the application alsospecifies an expected DNS name, Email address or IP
address.
TLS servers rarely solicit client certificates, and even when they do, theygenerally don't perform a name
check against a reference identifier (expectedidentity), but rather extract the presented identity after
checking thecertificate chain. So TLS servers are generally not affected and the severityof the issue is
Moderate.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. (CVE-2024-6119)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
