DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' branch parses the number with `atoi(src)` and assigns it to the binder counter with no range check, so a statement containing ':2147483648' leaves the counter negative (-2147483648 with glibc, where atoi wraps). Each following '?' then expands through `sprintf(start, ":p%d", idx++)` to ':p-2147483648', 14 bytes with the terminating NUL where the buffer budgets 7. The placeholder limit added in 1.650 tests the counter against 99,999, which a negative counter passes. Any caller that preparses an untrusted statement into ':pN' style placeholders gets a heap out-of-bounds write that grows with the number of '?' marks following the poisoned placeholder. The '?' and '%s' return styles compare the parsed number against the expected sequence and error out, and are unaffected.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0945 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-73194:

    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.

    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.
