Description Pedro Sampaio 2020-09-09 16:20:02 UTC 
A flaw was found in perl-dbi before version 1.628. A problem occurs when a user-defined function requires a non-trivial amount of memory and the perl stack gets reallocated.

Statement:

perl-DBI as shipped in Red Hat Enterprise Linux 8, rhscl-3 rh-perl526-perl-DBI and rhscl-3 rh-perl530-perl-DBI are notaffected by this flaw as the vulnerable code has already been patched in versions of perl-DBI shipped in these products.
