Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU49973
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3177
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary within the PyCArg_repr in _ctypes/callproc.c. A remote attacker can pass specially crafted input to the Python applications that accept floating-point numbers as untrusted input, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.

EUVDB-ID: #VU50621
Risk: Medium
CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-27619
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to Python executed eval() function on the code, retrieved via HTTP protocol in Lib/test/multibytecodec_support.py CJK codec tests. A remote attacker with ability to intercept network traffic can perform a Man-in-the-Middle (MitM) attack and execute arbitrary Python code on the system.
