Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU65287
Risk: Medium
CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-29187
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions. A remote user can bypass implemented security restrictions and privilege escalation on the system when navigating as root into a shared tmp directory owned by the victim, but where an attacker can create a git repository.
MitigationInstall update from vendor's website.
Vulnerable software versionsApple Xcode: 13.0 - 14.0.1
External linkshttp://support.apple.com/en-us/HT213496
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Input validation error
EUVDB-ID: #VU68517
Risk: Low
CVSSv3.1: 2.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-39253
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to the way Git handles hardlinks when performing a local clone. A remote attacker can trick the victim into clocking a malicious repository and create or copy hardlinks to critical files on the system, which can result in sensitive information exposure.
Install update from vendor's website.

3) Heap-based buffer overflow
EUVDB-ID: #VU68518
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-39260
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the "git shell" command when handling untrusted input. A remote attacker can trick the victim to execute the affected command against a malicious repository, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall update from vendor's website.

4) Code Injection
EUVDB-ID: #VU68898
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-42797
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to improper input validation within the IDE Xcode Server. A local application can send specially crafted data to the server and execute arbitrary code with root privileges.
