3) Buffer overflow
EUVDB-ID: #VU61671
Risk: Medium
CVSSv4.0: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2018-25032
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's website.

4) Buffer overflow
EUVDB-ID: #VU56217
Risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-3634
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 error when handling shared secrets. A remote attacker can supply a shared secret of a different size, trigger a memory corruption during the second key re-exchange and crash the application or potentially execute arbitrary code.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Infinite loop
EUVDB-ID: #VU59089
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3737
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop. A remote attacker who controls a malicious server can force the client to enter an infinite loop on a 100 Continue response.

6) Server-Side Request Forgery (SSRF)
EUVDB-ID: #VU61681
Risk: Medium
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-4189
CWE-ID:
CWE-918 - Server-Side Request Forgery (SSRF)
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the FTP (File Transfer Protocol) client library when using it in PASV (passive) mode. A remote attacker can set up a malicious FTP server, trick the FTP client in Python into connecting back to a given IP address and port, which can lead to FTP client scanning ports which otherwise would not have been possible.
