Description
This security bulletin contains information about 8 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2021-23139)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the CGI interface. A remote attacker can send a specially crafted request to the application and perform a denial of service (DoS) attack.
2) Stack-based buffer overflow (CVE-ID: CVE-2021-42012)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error. A local user can run a specially crafted program to trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.
3) Execution with unnecessary privileges (CVE-ID: CVE-2021-42104)
CWE-ID: CWE-250 - Execution with Unnecessary Privileges
