CVE-2019-19334 not yet assigned priority: Debian including 1 source packages (libyang), 4 status rows across 4 suites (bullseye, forky, sid, trixie): resolved 4.
In all versions of libyang before 1.0-r5, a stack-based buffer overflow was discovered in the way libyang parses YANG files with a leaf of type "identityref". An application that uses libyang to parse untrusted YANG files may be vulnerable to this flaw, which would allow an attacker to cause a denial of service or possibly gain code execution.
