Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-29499)
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. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2023-32611)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the g_variant_byteswap() function. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2023-32636)
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. A remote attacker can pass specially crafted GVariants to the application and perform a denial of service (DoS) attack.
4) Heap-based buffer overflow (CVE-ID: CVE-2023-32643)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the g_variant_serialised_get_child() function. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Resource exhaustion (CVE-ID: CVE-2023-32665)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Input validation error (CVE-ID: CVE-2023-1667)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to multiple errors in kex implementation, related to kex guessing algorithm. A remote attacker can bypass implemented security restrictions.
7) Improper Authentication (CVE-ID: CVE-2023-2283)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error within the pki_verify_data_signature() function in pki_crypto.c. The pki_key_check_hash_compatible() function can return SSH_OK value if memory allocation error happens later in the function. The A remote attacker can bypass authentication process and gain unauthorized access to the system.
8) Resource exhaustion (CVE-ID: CVE-2020-11080)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing HTTP/2 SETTINGS frames. A remote attacker can trigger high CPU load by sending large HTTP/2 SETTINGS frames and perform a denial of service (DoS) attack.
9) Improper Certificate Validation (CVE-ID: CVE-2023-31484)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to missing verification of the TLS certificate when downloading distributions. A remote attacker can perform MitM attack and trick the application into downloading a malicious file.
10) Input validation error (CVE-ID: CVE-2023-24329)
The vulnerability allows a remote attacker to bypass implemented filters.
The vulnerability exists due to insufficient validation of URLs that start with blank characters within urllib.parse component of Python. A remote attacker can pass specially crafted URL to bypass existing filters.
