"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-2022:0173 advisory.

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

    CVE-2020-35527:
    In SQLite 3.31.1, there is an out of bounds access problem through ALTER TABLE for views that have a
    nested FROM clause.

    CVE-2020-35525:
    In SQlite 3.31.1, a potential null pointer derreference was found in the INTERSEC query processing.

    CVE-2019-19645:
    alter.c in SQLite through 3.30.1 allows attackers to trigger infinite recursion via certain types of self-
    referential views in conjunction with ALTER TABLE statements.

    CVE-2019-19880:
    exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference
    because constant integer values in ORDER BY clauses of window definitions are mishandled.

    CVE-2019-5827:
    Integer overflow in SQLite via WebSQL in Google Chrome prior to 74.0.3729.131 allowed a remote attacker to
    potentially exploit heap corruption via a crafted HTML page.

    CVE-2019-13750:
    Insufficient data validation in SQLite in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to
    bypass defense-in-depth measures via a crafted HTML page.

    CVE-2019-13751:
    Uninitialized data 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-2019-19603:
    SQLite 3.30.1 mishandles certain SELECT statements with a nonexistent VIEW, leading to an application
    crash.

    CVE-2020-13435:
    SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.

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