Summary

OpenSSL is prone to a denial of service (DoS) vulnerability.

Insight

Insight

Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Reported by OSS-fuzz.

Affected Software

Affected Software

OpenSSL version 1.0.2b through 1.0.2n and 1.1.0 through 1.1.0g.

Detection Method

Detection Method

Checks if a vulnerable version is present on the target host.

Solution

Solution

Update to version 1.0.2o, 1.1.0h or later.
