Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2025-3360)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow with the g_date_time_new_from_iso8601() function when parsing a long invalid ISO 8601 timestamp. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
2) Integer overflow (CVE-ID: CVE-2025-13601)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to integer overflow within the g_escape_uri_string() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service attack.
3) Buffer overflow (CVE-ID: CVE-2025-14087)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the bytestring_parse() and string_parse() functions of the GVariant parser when processing maliciously crafted input strings. A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Integer overflow (CVE-ID: CVE-2025-6052)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in GString when handling long string. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
5) Out-of-bounds read (CVE-ID: CVE-2025-7039)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the get_tmp_file() function in glib/gfileutils.c. A local user can trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
