Name of the Vulnerable Software and Affected Versions perl-DBI versions prior to 1.643

Description The issue is related to a buffer overflow in the DBI component of the Perl programming language interpreter. This could allow an attacker to compromise data integrity and cause a denial of service. A local attacker who can supply a string longer than 300 characters could cause an out-of-bounds write.

Recommendations For versions prior to 1.643, update to version 1.643 or later to resolve the issue. As a temporary workaround, consider restricting input string lengths to prevent out-of-bounds writes.
