Constructed ASN.1 types with a recursive definition could exceed the stack (CVE-2018-0739) ========================================================================================== Severity: Moderate 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. OpenSSL 1.1.0 users should upgrade to 1.1.0h OpenSSL 1.0.2 users should upgrade to 1.0.2o This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz project. The fix was developed by Matt Caswell of the OpenSSL development team.
Please note that this is *not* a new issue in OpenSSL; this tracker is so we can use the CVE for libtomcrypt / dropbear too.
