Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) UNIX symbolic link following (CVE-ID: CVE-2021-28153)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue, when g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
2) 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.
3) 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.
4) 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.
5) 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.
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.
