Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-7550)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Out-of-bounds write (CVE-ID: CVE-2020-7551)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
3) Heap-based buffer overflow (CVE-ID: CVE-2020-7552)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can 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-2020-7553)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can 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) Buffer overflow (CVE-ID: CVE-2020-7554)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Out-of-bounds write (CVE-ID: CVE-2020-7555)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
7) Out-of-bounds write (CVE-ID: CVE-2020-7556)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
8) Out-of-bounds Read (CVE-ID: CVE-2020-7557)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
9) Out-of-bounds write (CVE-ID: CVE-2020-7558)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when a malicious CGF (Configuration Group File) is imported to IGSS Definition. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
