Name of the Vulnerable Software and Affected Versions Perl versions 5.8.2 through 5.16.x

Description The issue is related to the rehash mechanism in Perl, which is associated with resource management errors. It allows remote attackers to cause a denial of service, resulting in memory consumption and a crash, by using a crafted hash key. This can be exploited by context-dependent attackers.

Recommendations For Perl versions 5.8.2 through 5.16.x, consider disabling the rehash mechanism as a temporary workaround until a patch is available. Restrict access to the hash key functionality to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
