Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Double free (CVE-ID: CVE-2025-5914)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the archive_read_format_rar_seek_data() function. A remote attacker can pass specially crafted data to the application, trigger a double free error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Resource exhaustion (CVE-ID: CVE-2025-8677)
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 querying for data within a specially crafted zone containing certain malformed DNSKEY records. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Insufficient verification of data authenticity (CVE-ID: CVE-2025-40778)
The vulnerability allows a remote attacker to poison DNS cache.
The vulnerability exists due to insufficient verification of data authenticity when accepting records from answers. A remote attacker can inject forged data into the cache leading to DNS cache poisoning.
4) Predictable Seed in Pseudo-Random Number Generator (PRNG) (CVE-ID: CVE-2025-40780)
The vulnerability allows a remote attacker to poison DNS cache.
The vulnerability exists due to weakness in the Pseudo Random Number Generator (PRNG). A remote attacker can predict the source port and query ID that BIND will use and perform DNS cache poisoning attacks.
5) Resource exhaustion (CVE-ID: CVE-2025-59375)
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 large dynamic memory allocations via a small document and perform a denial of service (DoS) attack.
6) Out-of-bounds read (CVE-ID: CVE-2025-5318)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the sftp_handle() function. A remote user can trigger an out-of-bounds read error and read contents of memory on the system.
7) Use-after-free (CVE-ID: CVE-2025-11234)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in websocket handshake code in /io/channel-websock.c. A remote attacker with network access to the VNC WebSocket port can perform a denial of service during the WebSocket handshake prior to the VNC client authentication.
