The remote Ubuntu 20.04 LTS / 21.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5305-1 advisory.

  • MariaDB before 10.7.2 allows an application crash because it does not recognize that SELECT_LEX::nest_level is local to each VIEW. (CVE-2021-46659)

  • MariaDB through 10.5.9 allows an application crash in find_field_in_tables and find_order_in_list via an unused common table expression (CTE). (CVE-2021-46661)

  • MariaDB through 10.5.13 allows a ha_maria::extra application crash via certain SELECT statements.
    (CVE-2021-46663)

  • MariaDB through 10.5.9 allows an application crash in sub_select_postjoin_aggr for a NULL value of aggr.
    (CVE-2021-46664)

  • MariaDB through 10.5.9 allows a sql_parse.cc application crash because of incorrect used_tables expectations. (CVE-2021-46665)

  • MariaDB through 10.5.9 allows an application crash via certain long SELECT DISTINCT statements that improperly interact with storage-engine resource limitations for temporary data structures.
    (CVE-2021-46668)

  • MariaDB CONNECT Storage Engine Stack-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB.
    Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16191.
    (CVE-2022-24048)

  • MariaDB CONNECT Storage Engine Use-After-Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16207. (CVE-2022-24050)

  • MariaDB CONNECT Storage Engine Format String Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16193. (CVE-2022-24051)

  • MariaDB CONNECT Storage Engine Heap-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB.
    Authentication is required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16190.
    (CVE-2022-24052)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
