Name of the Vulnerable Software and Affected Versions Perl version 5.10.1

Description The issue is related to errors in resource release in the Perl programming language interpreter. It may allow a remote attacker to cause a denial of service. Specifically, the problem arises when a UTF-8 character with a large, invalid codepoint is not properly handled during a regular-expression match, potentially leading to an application crash.

Recommendations For Perl version 5.10.1, consider disabling the use of UTF-8 characters with large codepoints in regular expressions until a patch is available. As a temporary workaround, restrict the input of UTF-8 characters to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
