DBI versions before 1.652 for Perl allow a heap out-of-bounds write on 32-bit perl via an integer wraparound in the output buffer size computed by preparse. preparse reserves its output buffer with `newSV(strlen(statement) * 7 + 16)`, budgeting seven output bytes per input byte for the longest ':p99999' expansion. The product is computed in STRLEN, which is 32 bits wide on a 32-bit perl build, so a statement of 613,566,757 bytes multiplies to 4,294,967,299, wraps modulo 2^32 to 3, and reserves 19 bytes. The parser then copies the statement out through a raw pointer with no capacity check, writing the whole 585 MB input past the end of the allocation. The 99,999 placeholder limit does not bound this path, which is reached by ordinary non-placeholder content. Any caller that passes an untrusted statement of that length to preparse on a 32-bit perl gets a heap out-of-bounds write of attacker controlled bytes. Builds with a 64-bit STRLEN are not affected, since the wrap there needs a statement of about 2.3 exabytes.

The remote Debian 11 / 12 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4764 advisory.

    Multiple vulnerabilities were discovered in libdbi-perl, the Perl     Database Interface (DBI), which may lead to arbitrary code execution,     denial of service, file-backed filter bypass or path traversal.

    CVE-2026-14380

        It was found that missing input validation when interpolating the         package name in a string `eval` may lead to arbitrary Perl code         execution from an attacker able controlling the Profile attribute,         for instance via the `DBI_PROFILE` environment variable or a DSN         driver-attribute clause `dbi:Driver(Profile=>SPEC):db`.

    CVE-2026-14739

        It was found that preparsing SQL statements with an excessively high         (over one million) number of placeholders could lead to heap         overflow.

        This update sets a hard limit of 99999 placeholders.

    CVE-2026-14740

        It was found that preparsing an SQL statement starting with a         comment line could lead to an out-of-bounds read by one byte.

    CVE-2026-15043

        It was found that DBI::SQL::Nano, DBI's built-in mini-SQL engine,         evaluated `WHERE` predicates by incorrectly inverting `<=` and `>=`         SQL operators on text, which may lead to file-backed filter bypass.

    CVE-2026-15392

        It was found that DBD::File did not check whether the table file is         a symbolic link, which may lead to path traversal if the target         points outside the `f_dir` and `f_dir_search` directories.

        This issue stems from an incomplete fix for CVE-2014-10401 and         CVE-2014-10402.

    CVE-2026-60081

        It was found that DBI::ProfileData did not limit the path index when         parsing a profile-dump file, which may lead to denial of service.

        This updates adds a configurable maximum path depth         `$DBI::Profile::MAX_PATH_DEPTH`, with a default value of 256.

    CVE-2026-60082

        It was found that missing statement handle consistency checks could         lead to an out-of-bounds read when a statement handle had no fields         and the source row was non-empty.

    CVE-2026-73193

        A heap out-of-bounds write issue was found on 32-bit platforms due to         integer overflow in the output buffer size computed by the `preparse()`         function.

        This updates limits the size of SQL statements to 292 MiB.

    CVE-2026-73194

        A heap out-of-bounds write issue was found due to unvalidated         numeric placeholder in the `preparse()` function.

        This issue stems from an incomplete fix for CVE-2026-14739.

    For Debian 11 bullseye, these problems have been fixed in version     1.643-3+deb11u2.

    For Debian 12 bookworm, these problems have been fixed in version     1.643-4+deb12u2.

    We recommend that you upgrade your libdbi-perl packages.

    Several vulnerabilities were discovered in libdbi-perl, a Perl framework     that provides a common interface to access various backend databases in     a uniform manner, which could result in denial of service, path     traversal, bypass of file-backed filters or the execution of arbitrary     code.

    For the stable distribution (trixie), these problems have been fixed in     version 1.652-2~deb13u1.

    We recommend that you upgrade your libdbi-perl packages.
