Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2023-27882)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the HTTP Server form boundary functionality. A remote attacker can pass specially crafted data to the application, 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) Buffer overflow (CVE-ID: CVE-2023-31247)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the HTTP Server Host header parsing functionality. 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.
3) Buffer overflow (CVE-ID: CVE-2023-28391)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the HTTP Server header parsing functionality. 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.
4) Out-of-bounds write (CVE-ID: CVE-2023-24585)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the HTTP Server functionality. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.
5) Heap-based buffer overflow (CVE-ID: CVE-2023-25181)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the HTTP Server functionality. A remote attacker can pass specially crafted data to the application, 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.
6) Buffer overflow (CVE-ID: CVE-2023-28379)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the HTTP Server form boundary functionality. 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.
