Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) CRLF injection

EUVDB-ID: #VU31958

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-18348

CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with (specifically in the host component of a URL) followed by an HTTP header. This is similar to the CVE-2019-9740 query string issue and the CVE-2019-9947 path string issue. (This is not exploitable when glibc has CVE-2016-10739 fixed.)

Mitigation

Update the affected package python3 to the latest version.

2) 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.

4) Integer overflow

EUVDB-ID: #VU68887

Risk: High

CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-37454

CWE-ID: CWE-190 - Integer overflow

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the Keccak XKCP SHA-3 reference implementation. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system or eliminate expected cryptographic properties.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package python3 to the latest version.
