libyang: stack-based buffer overflow in make_canonical when bits leaf type is used
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD. Niedriger laut Red Hat (hoch), Oracle (hoch).
Beschreibung
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 "bits". 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.
