Published: 2020-01-23 13:01:56
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:S/C:P/I:P/A:C

Summary:
The remote host is missing an update for the Huawei EulerOS 'subversion' Linux Distribution Package(s) announced via the EulerOS-SA-2019-2504 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
Apache Subversion's mod_dontdothat module and HTTP clients 1.4.0 through 1.8.16, and 1.9.0 through 1.9.4 are vulnerable to a denial-of-service attack caused by exponential XML entity expansion. The attack can cause the targeted process to consume an excessive amount of CPU resources or memory.(CVE-2016-8734) Integer overflow in util.c in mod_dav_svn in Apache Subversion 1.7.x, 1.8.x before 1.8.15, and 1.9.x before 1.9.3 allows remote authenticated users to cause a denial of service (subversion server crash or memory consumption) and possibly execute arbitrary code via a skel-encoded request body, which triggers an out-of-bounds read and heap-based buffer overflow.(CVE-2015-5343) The canonicalize_username function in svnserve/cyrus_auth.c in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4, when Cyrus SASL authentication is used, allows remote attackers to authenticate and bypass intended access restrictions via a realm string that is a prefix of an expected repository realm string.(CVE-2016-2167) The req_check_access function in the mod_authz_svn module in the httpd server in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4 allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) via a crafted header in a (1) MOVE or (2) COPY request, involving an authorization check.(CVE-2016-2168)

Affected Versions:
'subversion' Linux Distribution Package(s) on Huawei EulerOS V2.0SP2.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
