Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2025-11083)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the elf_swap_shdr() function in bfd/elfcode.h. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.
2) Out-of-bounds read (CVE-ID: CVE-2025-9086)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when reading cookie path. A malicious server can set a specially crafted cookie path using the secure keyword, trigger an out-of-bounds read error and crash the application.
3) Out-of-bounds read (CVE-ID: CVE-2025-64720)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the png_image_read_composite() function when processing palette images with PNG_FLAG_OPTIMIZE_ALPHA enabled. A remote attacker can pass a specially crafted image file to the application, trigger an out-of-bounds read error and read contents of memory on the system.
4) Heap-based buffer overflow (CVE-ID: CVE-2025-65018)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the png_image_finish_read() function when processing 16-bit interlaced PNGs with 8-bit output format. A remote attacker can pass a specially crafted image file 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.
5) Out-of-bounds read (CVE-ID: CVE-2025-66293)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the png_image_read_composite() function. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
6) Improper locking (CVE-ID: CVE-2025-39697)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the nfs_page_set_inode_ref(), nfs_page_group_lock() and nfs_inode_remove_request() functions in fs/nfs/write.c, within the nfs_page_group_unlock() function in fs/nfs/pagelist.c. A local user can perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2025-39971)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the i40e_vc_config_queues_msg() function in drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c. A local user can perform a denial of service (DoS) attack.
