Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Link following (CVE-ID: CVE-2024-45339)
The vulnerability allows a local user to overwrite arbitrary files on the system.
The vulnerability exists due to insecure link following when writing log files. A local user can point a symbolic link to a critical file on the system and overwrite it with the log data.
2) NULL pointer dereference (CVE-ID: CVE-2022-49977)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the ftrace_startup() function in kernel/trace/ftrace.c. A local user can perform a denial of service (DoS) attack.
3) Insufficient verification of data authenticity (CVE-ID: CVE-2024-34397)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to missing authorization for D-Bus signals. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service.
4) Off-by-one (CVE-ID: CVE-2024-52533)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an off-by-one error in gio/gsocks4aproxy.c when handling responses from SOCKS4 proxy. A remote attacker can trick the victim into connecting to a malicious SOCKS4 proxy server, trigger an off-by-one error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Insecure temporary file (CVE-ID: CVE-2024-54661)
The vulnerability allows a local user to overwrite arbitrary files on the system.
The vulnerability exists due to usage of a predictable temporary file name in readline.sh. A local user can create a symbolic link from the temporary file to an arbitrary files on the system and overwrite it with the application's output, corrupting the file.
6) Integer overflow (CVE-ID: CVE-2025-4373)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the g_string_insert_unichar() function in glib/gstring.c. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Acceptance of Extraneous Untrusted Data With Trusted Data (CVE-ID: CVE-2025-5994)
The vulnerability allows a remote attacker to perform cache poisoning attacks.
The vulnerability exists due to a logic error in the EDNS Client Subnet (ECS) implementation. A remote attacker can perform cache poisoning attacks against Unbound servers with ECS support, a.k.a. Rebirthday Attack.
Successful exploitation of the vulnerability requires that the server is compiled with '--enable-subnet' and configured to send ECS information to upstream name servers with at least one of the 'send-client-subnet', 'client-subnet-zone' or 'client-subnet-always-forward' options.
8) Improper access control (CVE-ID: CVE-2025-6020)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper access restrictions within the pam_namespace module when handling user-controlled paths. A local user can use specially crafted symlinks and race conditions to execute arbitrary code as root.
9) Integer overflow (CVE-ID: CVE-2025-6021)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the xmlBuildQName() function in tree.c . A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Buffer overflow (CVE-ID: CVE-2025-6965)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
11) Buffer overflow (CVE-ID: CVE-2025-21905)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory corruption within the iwl_parse_tlv_firmware() function in drivers/net/wireless/intel/iwlwifi/iwl-drv.c. A local user can perform a denial of service (DoS) attack.
12) Input validation error (CVE-ID: CVE-2025-21919)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the child_cfs_rq_on_list() function in kernel/sched/fair.c. A local user can perform a denial of service (DoS) attack.
13) Race condition (CVE-ID: CVE-2025-40909)
The vulnerability allows a local user to tamper with application's behavior.
The vulnerability exists due to a race condition if a directory handle is open at thread creation. A local user can exploit the race and force the application to load code or access files from unexpected location.
14) Integer overflow (CVE-ID: CVE-2025-47268)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an integer overflow within the ping command when handling ICMP Echo Reply packets. A remote attacker can trick the victim to ping a malicious server, trigger an integer overflow and crash the application.
15) Path traversal (CVE-ID: CVE-2025-47273)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to input validation error when processing directory traversal sequences in package_index.py. A remote attacker can trick the victim into installing a specially crafted script and overwrite arbitrary files on the system, leading to code execution.
16) Use-after-free (CVE-ID: CVE-2025-49794)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the xmlSchematronGetNode() function when processing XPath expressions in Schematron schema elements schematron.c. A remote attacker can pass specially crafted XML input to the application and perform a denial of service (DoS) attack.
17) Type Confusion (CVE-ID: CVE-2025-49796)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error within the xmlSchematronFormatReport() function when processing sch:name elements in schematron.c. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and crash the application.
