DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders. The preparse method expands SQL placeholder characters to numbered binders of the form :pN, but only allocates three characters per binder in the buffer. Placeholders 10-99 require four characters, 100-999 require five characters, et cetera.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4649 advisory.

    Package        : libdbi-perl     Version        : 1.643-3+deb11u1     CVE ID         : CVE-2026-9698 CVE-2026-10879

    Two vulnerabilities were discovered in libdbi-perl, the Perl Database     Interface (DBI), which may lead to denial of service or potentially     execution of arbitrary code.

    CVE-2026-9698

        Error messages that were returned when `RaiseError`, `PrintError` or         `HandleError` were set were written to a 200-byte buffer without a         length limit.  Attackers that can influence the error text in an         application could therefore trigger a buffer overflow.

    CVE-2026-10879

        The preparse method expands SQL placeholder characters to numbered         binders of the form `:pN`, but only allocates three characters per         binder in the buffer, leading to an out-of-bounds write when the         statement has 10 or more binders.

    For Debian 11 bullseye, these problems have been fixed in version     1.643-3+deb11u1.

    We recommend that you upgrade your libdbi-perl packages.

    It was discovered that the Perl DBI module incorrectly handled certain error messages. An attacker could     use this issue to cause applications using the Perl DBI module to crash, resulting in a denial of service,     or possibly execute arbitrary code. (CVE-2026-9698)

    It was discovered that the Perl DBI module incorrectly handled memory when preparsing SQL statements that     included more than nine binders.

    Package        : libdbi-perl     CVE ID         : CVE-2026-9698 CVE-2026-10879

    Two vulnerabilities were discovered in libdbi-perl, a Perl framework     that provides a common interface to access various backend databases in     a uniform manner, which may result in denial of service, or potentially     the execution of arbitrary code.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 1.643-4+deb12u1.

    For the stable distribution (trixie), these problems have been fixed in     version 1.647-1+deb13u1.

    We recommend that you upgrade your libdbi-perl packages.
