EulerOS Virtualization for ARM 64 3.0.2.0 : git (EulerOS-SA-2020-1537)

critical Nessus Plugin ID 136240

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the git packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - Arbitrary command execution is possible in Git before 2.20.2, 2.21.x before 2.21.1, 2.22.x before 2.22.2, 2.23.x before 2.23.1, and 2.24.x before 2.24.1 because a 'git submodule update' operation can run commands found in the .gitmodules file of a malicious repository.(CVE-2019-19604)

 - An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, and v2.14.6. Recursive clones are currently affected by a vulnerability that is caused by too-lax validation of submodule names, allowing very targeted attacks via remote code execution in recursive clones.(CVE-2019-1387)

 - A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka 'Git for Visual Studio Remote Code Execution Vulnerability'.
 This CVE ID is unique from CVE-2019-1349, CVE-2019-1350, CVE-2019-1352, CVE-2019-1387.(CVE-2019-1354)

 - An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, and v2.14.6. When running Git in the Windows Subsystem for Linux (also known as 'WSL') while accessing a working directory on a regular Windows drive, none of the NTFS protections were active.(CVE-2019-1353)

 - A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka 'Git for Visual Studio Remote Code Execution Vulnerability'.
 This CVE ID is unique from CVE-2019-1349, CVE-2019-1350, CVE-2019-1354, CVE-2019-1387.(CVE-2019-1352)

 - A tampering vulnerability exists when Git for Visual Studio improperly handles virtual drive paths, aka 'Git for Visual Studio Tampering Vulnerability'.(CVE-2019-1351)

 - A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka 'Git for Visual Studio Remote Code Execution Vulnerability'.
 This CVE ID is unique from CVE-2019-1349, CVE-2019-1352, CVE-2019-1354, CVE-2019-1387.(CVE-2019-1350)

 - A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input, aka 'Git for Visual Studio Remote Code Execution Vulnerability'.
 This CVE ID is unique from CVE-2019-1350, CVE-2019-1352, CVE-2019-1354, CVE-2019-1387.(CVE-2019-1349)

 - An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, and v2.14.6. The --export-marks option of git fast-import is exposed also via the in-stream command feature export-marks=... and it allows overwriting arbitrary paths.(CVE-2019-1348)

 - Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. Git uses external 'credential helper' programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that contain an encoded newline can inject unintended values into the credential helper protocol stream, causing the credential helper to retrieve the password for one server (e.g., good.example.com) for an HTTP request being made to another server (e.g., evil.example.com), resulting in credentials for the former being sent to the latter. There are no restrictions on the relationship between the two, meaning that an attacker can craft a URL that will present stored credentials for any host to a host of their choosing. The vulnerability can be triggered by feeding a malicious URL to git clone. However, the affected URLs look rather suspicious the likely vector would be through systems which automatically clone URLs not visible to the user, such as Git submodules, or package systems built around Git. The problem has been patched in the versions published on April 14th, 2020, going back to v2.17.x. Anyone wishing to backport the change further can do so by applying commit 9a6bbee (the full release includes extra checks for git fsck, but that commit is sufficient to protect clients against the vulnerability). The patched versions are:
 2.17.4, 2.18.3, 2.19.4, 2.20.3, 2.21.2, 2.22.3, 2.23.2, 2.24.2, 2.25.3, 2.26.1.(CVE-2020-5260)

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

Solution

Update the affected git packages.
