Name of the Vulnerable Software and Affected Versions: Yara (affected versions not specified)

Description: The issue is related to a heap-use-after-free error, which occurs when the program attempts to access memory that has already been freed. This can lead to a crash. The error is specifically triggered in the yr re ast split at chaining point function, which is called by yr parser reduce string declaration and ultimately by yara yyparse.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
