perl-dbi: Multiple vulnerabilities (CVE-2020-14392, CVE-2020-14393)
CVE-2020-14392: Memory corruption in XS functions when Perl stack is reallocated
A flaw was found in perl-dbi before version 1.643. Macro ST() returns pointer to Perl stack. Other Perl functions which use Perl stack (e.g. eval) may reallocate Perl stack and therefore pointer returned by ST() macro is invalid which may lead to memory corruption.
