NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-uefi-aarch64 package and not the qemu-uefi-aarch64 package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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).
