1) Input validation error (CVE-ID: CVE-2023-25180)

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 handling a serialised variant. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Input validation error (CVE-ID: CVE-2023-24593)

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 handling a text-form variant. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) 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.


4) Input validation error (CVE-ID: CVE-2023-29499)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

5) 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.


6) 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.


7) 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.
