Name of the Vulnerable Software and Affected Versions Perl version 5.34.0

Description The issue is related to the S find uninit var function in the sv.c file of the Perl interpreter, which is associated with a buffer overflow. This can allow a remote attacker to execute arbitrary code or lead to local privilege escalation.

Recommendations For Perl version 5.34.0, consider disabling the S find uninit var function as a temporary workaround until a patch is available. Restrict access to the sv.c module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
