Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Type conversion

EUVDB-ID: #VU67760

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-10735

CWE-ID: CWE-704 - Type conversion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a type confusion in algorithms with quadratic time complexity when using non-binary bases within the int() call. A remote attacker can pass specially crafted data to the affected application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package python3 to the latest version.
