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-2022:0178 advisory.

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

    CVE-2022-24070:
    Subversion's mod_dav_svn is vulnerable to memory corruption. While looking up path-based authorization     rules, mod_dav_svn servers may attempt to use memory which has already been freed. Affected Subversion     mod_dav_svn servers 1.10.0 through 1.14.1 (inclusive). Servers that do not use mod_dav_svn are not     affected.
    CVE-2020-17525:
    Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the     AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL.
    This can lead to disruption for users of the service. This issue was fixed in mod_dav_svn+mod_authz_svn     servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7     CVE-2019-0203:
    In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server     process may exit when a client sends certain sequences of protocol commands. This can lead to disruption     for users of the server.

This update for subversion fixes the following issues :

CVE-2020-17525: A null-pointer-dereference has been found in mod_authz_svn that results in a remote unauthenticated Denial-of-Service in some server configurations (bsc#1181687).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Thomas Akesson discovered a remotely triggerable vulnerability in the mod_authz_svn module in Subversion, a version control system. When using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option an unauthenticated remote client can take advantage of this flaw to cause a denial of service by sending a request for a non-existing repository URL.
