Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2019-1387)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.
2) Input validation error (CVE-ID: CVE-2019-1354)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.
3) Input validation error (CVE-ID: CVE-2019-1352)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.
4) Absolute Path Traversal (CVE-ID: CVE-2019-1351)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to the Git for Visual Studio improperly handles virtual drive paths. A remote attacker can clone a file using a specially crafted path and write arbitrary files and directories to certain locations on a vulnerable system.
5) Input validation error (CVE-ID: CVE-2019-1350)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.
6) Input validation error (CVE-ID: CVE-2019-1349)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.
