Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-45960)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the storeAtts() function in xmlparse.c. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Integer overflow (CVE-ID: CVE-2021-46143)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the doProlog() function in xmlparse.c. 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.
3) Integer overflow (CVE-ID: CVE-2022-22822)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the addBinding() function in xmlparse.c. 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.
4) Integer overflow (CVE-ID: CVE-2022-22823)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the build_model() function in xmlparse.c. 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.
5) Integer overflow (CVE-ID: CVE-2022-22824)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the defineAttribute() function in xmlparse.c. 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.
6) Integer overflow (CVE-ID: CVE-2022-22825)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the lookup() function in xmlparse.c. 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.
7) Integer overflow (CVE-ID: CVE-2022-22826)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the nextScaffoldPart() function in xmlparse.c. 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.
8) Integer overflow (CVE-ID: CVE-2022-22827)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the storeAtts() function in xmlparse.c. 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.
9) Integer overflow (CVE-ID: CVE-2022-23852)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. 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.
10) 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.
11) 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.
12) 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.
