Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Code Injection (CVE-ID: CVE-2022-25235)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to the affected application lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Input validation error (CVE-ID: CVE-2022-25236)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper protection against insertion of namesep characters into namespace URIs in xmlparse.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Stack-based buffer overflow (CVE-ID: CVE-2022-25313)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in build_model. A remote unauthenticated attacker can 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-2022-25314)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in copyString. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
5) Integer overflow (CVE-ID: CVE-2022-25315)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in storeRawNames function. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
