Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Access of Uninitialized Pointer (CVE-ID: CVE-2026-21275)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error when handling untrusted data. A remote attacker can trick the victim into opening a specially crafted file, trigger access to an uninitialized pointer and execute arbitrary code on the system.
2) Access of Uninitialized Pointer (CVE-ID: CVE-2026-21276)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error when handling untrusted data. A remote attacker can trick the victim into opening a specially crafted file, trigger access to an uninitialized pointer and execute arbitrary code on the system.
3) Heap-based buffer overflow (CVE-ID: CVE-2026-21277)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim into opening a specially crafted file, 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.
4) Heap-based buffer overflow (CVE-ID: CVE-2026-21304)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim into opening a specially crafted file, 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-2026-21278)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. 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.
