Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2026-28689)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a time-of-check, time-of-use (TOCTOU) race condition in domain="path" authorization. A remote user can bypass authentication on the system.
2) Stack-based buffer overflow (CVE-ID: CVE-2026-30929)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in MagnifyImage. A remote unauthenticated attacker can trigger stack-based buffer overflow and corrupt the stack on the target system.
3) Heap-based buffer overflow (CVE-ID: CVE-2026-30931)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the UHDR encoder. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
4) Heap-based buffer overflow (CVE-ID: CVE-2026-30936)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the WaveletDenoiseImage method. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
5) Heap-based buffer overflow (CVE-ID: CVE-2026-32636)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the NewXMLTree method. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
6) Out-of-bounds write (CVE-ID: CVE-2026-33535)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the X11 display interaction path. A remote attacker can trigger an out-of-bounds write and perform a denial of service (DoS) attack the target system.
7) Stack-based buffer overflow (CVE-ID: CVE-2026-33536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in InterpretImageFilename. A remote unauthenticated attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
