MEDIUM 6.5EPSS 1.86%
Does this matter?
Lower severity and a low EPSS score (1.86%). Track it; it rarely justifies an emergency change on its own.
Description
An invalid memory access flaw is present in libyang before v1.0-r3 in the function resolve_feature_value() when an if-feature statement is used inside a bit. Applications that use libyang to parse untrusted input yang files may crash.
