Security Bulletin
This security bulletin contains information about 9 vulnerabilities.
EUVDB-ID: #VU64573
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-20107
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the mailcap module, which does not escape characters into commands discovered in the system mailcap file. A remote unauthenticated attacker can pass specially crafted data to the applications that call mailcap.findmatch with untrusted input and execute arbitrary OS commands on the target system.
Update the affected packages.

EUVDB-ID: #VU51604
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-28363
CWE-ID:
CWE-297 - Improper Validation of Certificate with Host Mismatch
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to urllib3 library for Python omits SSL certificate validation in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given
via proxy_config) doesn't verify the hostname of the certificate. This
means certificates for different servers that still validate properly
with the default urllib3 SSLContext will be silently accepted. A remote attacker can supply a valid SSL certificate for a different hostname and perform Man-in-the-Middle (MitM) attack.
Update the affected packages.

Risk: Low
CVSSv3.1: 3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-28861
CWE-ID:
CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in lib/http/server.py due to missing protection against multiple (/) at the beginning of URI path. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
MitigationUpdate the affected packages.
