Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory leak (CVE-ID: CVE-2025-28162)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in png_malloc_base() function. A remote attacker can supply a specially crafted image file to the application and force the library to leak memory.
2) Memory leak (CVE-ID: CVE-2025-28164)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in png_create_read_struct() function. A remote attacker can supply a specially crafted image file to the application and force the library to leak memory.
3) Out-of-bounds read (CVE-ID: CVE-2026-22695)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information or crash the application.
The vulnerability exists due to a boundary condition within the png_image_finish_read() function when reading 16-bit PNG images with 8-bit output format and non-minimal row stride. A remote attacker can supply a specially crafted PNG image file to the application, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
Note, the vulnerability exists due to an incomplete fix for #VU118777 (CVE-2025-65018).
