CyberRota Analysis
AI-GeneratedDBI versions prior to 1.654 for Perl are vulnerable due to improper handling of numeric values in the FetchHashKeyName attribute, which can lead to segmentation faults when these values are treated as string pointers. This vulnerability can be exploited by executing specific SQL queries, potentially causing application crashes. Developers and system administrators using affected DBI versions should prioritize updating to mitigate the risk of application instability.

Original NVD Description
DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName. fetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to an integer (IV) or floating-point (NV) value, that pointer is invalid, so reading the key name triggers a segmentation fault. This can be triggered with the following code: my $dbh = DBI->connect( "dbi:ExampleP:", "", "", { RaiseError => 0, PrintError => 0 } ); $dbh->{FetchHashKeyName} = 42; my $sth = $dbh->prepare("select mode, size, name from ."); $sth->execute; $sth->fetchrow_hashref;
