CVE-2018-0739 (GCVE-0-2018-0739)

Vulnerability from cvelistv5 – Published: 2018-03-27 21:00 – Updated: 2024-09-16 22:35

Title

Constructed ASN.1 types with a recursive definition could exceed the stack

Summary

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. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).

Severity

No CVSS data available.
