Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
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
Exploit availability: No
DescriptionThe 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.)
MitigationUpdate the affected package python to the latest version.

EUVDB-ID: #VU50814
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-23336
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform web cache spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input in django.utils.http.limited_parse_qsl() when parsing strings with a semicolon (";"). A remote attacker can pass specially crafted data to the application and perform a spoofing attack.
MitigationUpdate the affected package python to the latest version.
