"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0111 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2019-13734:
    Out of bounds write in SQLite in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to
    potentially exploit heap corruption via a crafted HTML page.

    CVE-2019-13752:
    Out of bounds read in SQLite in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to obtain
    potentially sensitive information from process memory via a crafted HTML page.

    CVE-2019-13753:
    Out of bounds read in SQLite in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to obtain
    potentially sensitive information from process memory via a crafted HTML page.

    CVE-2019-16168:
    In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application
    because of missing validation of a sqlite_stat1 sz field, aka a severe division by zero in the query
    planner.

    CVE-2019-19923:
    flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT
    JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect
    results).

    CVE-2019-19924:
    SQLite 3.30.1 mishandles certain parser-tree rewriting, related to expr.c, vdbeaux.c, and window.c. This
    is caused by incorrect sqlite3WindowRewrite() error handling.

    CVE-2019-19925:
    zipfileUpdate in ext/misc/zipfile.c in SQLite 3.30.1 mishandles a NULL pathname during an update of a ZIP
    archive.

    CVE-2019-19959:
    ext/misc/zipfile.c in SQLite 3.30.1 mishandles certain uses of INSERT INTO in situations involving
    embedded '\0' characters in filenames, leading to a memory-management error that can be detected by (for
    example) valgrind.

    CVE-2019-20218:
    selectExpander in select.c in SQLite 3.30.1 proceeds with WITH stack unwinding even after a parsing error.

    CVE-2019-5018:
    An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0.
    A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote
    code execution. An attacker can send a malicious SQL command to trigger this vulnerability.

    CVE-2019-8457:
    SQLite3 from 3.6.0 to and including 3.27.2 is vulnerable to heap out-of-bound read in the rtreenode()
    function when handling invalid rtree tables.

    CVE-2020-13434:
    SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

    CVE-2020-13630:
    ext/fts3/fts3.c in SQLite before 3.32.0 has a use-after-free in fts3EvalNextRow, related to the snippet
    feature.

    CVE-2020-13631:
    SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related
    to alter.c and build.c.

    CVE-2020-13632:
    ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo()
    query.

    CVE-2020-15358:
    In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy
    heap overflow because of misuse of transitive properties for constant propagation.

    CVE-2020-6405:
    Out of bounds read in SQLite in Google Chrome prior to 80.0.3987.87 allowed a remote attacker to obtain
    potentially sensitive information from process memory via a crafted HTML page.

    CVE-2020-9327:
    In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and
    segmentation fault because of generated column optimizations.
