Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2022-25647)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data passed to writeReplace() method. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
2) Deserialization of Untrusted Data (CVE-ID: CVE-2022-28948)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data in the Unmarshal function. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2018-25032)
The 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.
4) Buffer overflow (CVE-ID: CVE-2021-3634)
The 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 (CVE-ID: CVE-2021-3737)
The 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) (CVE-ID: CVE-2021-4189)
The 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.
