Amazon Linux 2 : git (ALAS-2023-1943)

critical Nessus Plugin ID 171819

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of git installed on the remote host is prior to 2.23.1-0. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1943 advisory.

- 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)

- 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)

- 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 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-2019-1350, CVE-2019-1354, CVE-2019-1387. (CVE-2019-1352)

- 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-2019-1352, 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. 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)

- 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update git' to update your system.
