NVD Description

Note: Versions mentioned in the description apply only to the upstream yara package and not the yara package as distributed by Ubuntu.

libyara/grammar.y in YARA 3.5.0 allows remote attackers to cause a denial of service (heap-based out-of-bounds read and application crash) via a crafted rule that is mishandled in the yara_yyparse function.
