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;

    Vulnerabilities were discovered in libdbi-perl, the Perl Database     Interface (DBI), which may lead to memory corruption, denial of service,     or arbitrary module load.

    CVE-2026-78030

        Harsh Raj Singhania discovered that an attacker able to choose DSN         fragments or request parameter can trigger arbitrary module load due         to the lack of connect attribute validation.

    CVE-2026-88815

        Harsh Raj Singhania discovered that sql_type_cast_svpv() incorrectly         treats numeric values as strings, which may lead to application         crash.

    CVE-2026-88816

        Harsh Raj Singhania discovered that FetchHashKeyName incorrectly         treats numeric values as strings, which may lead to application         crash.

    For Debian 12 bookworm, these problems have been fixed in version     1.643-4+deb12u3.

    We recommend that you upgrade your libdbi-perl packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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; (CVE-2026-88816)

Note that Nessus relies on the presence of the package as reported by the vendor.
