Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2025-14935)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the parsing of dimension names. A remote attacker can trick a victim to open 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.
2) Stack-based buffer overflow (CVE-ID: CVE-2025-14932)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the parsing of time units. A remote unauthenticated attacker can trick a victim to open a specially crafted file, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Stack-based buffer overflow (CVE-ID: CVE-2025-14934)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the parsing of variable names. A remote unauthenticated attacker can trick a victim to open a specially crafted file, trigger stack-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) Integer overflow (CVE-ID: CVE-2025-14933)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the parsing of NC variables. A remote attacker can trick a victim to open a specially crafted file, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Stack-based buffer overflow (CVE-ID: CVE-2025-14936)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the parsing of attribute names. A remote unauthenticated attacker can trick a victim to open a specially crafted file, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
