Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2015-1283)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.
2) Buffer overflow in Tenable Nessus (CVE-ID: CVE-2016-0718)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The vulnerability exists due to boundary error when handling malformed input documents. A remote unauthenticated attacker can trigger a buffer overflow in the Expat XML parser library and execute arbitrary code by sending specially crafted data to vulnerable server.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) XXE attack (CVE-ID: CVE-2016-4472)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to the overflow protection in Expat is removed by compilers with certain optimization settings. A remote attacker can supply specially crafted XML data and cause the service to crash.
The vulnerability exists due to incomplete fix for CVE-2015-1283 and CVE-2015-2716.
4) Out-of-bounds read (CVE-ID: CVE-2019-15903)
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing XML documents within the expat library. A remote attacker can create a specially crafted XML file, pass it to the affected application, trigger out-of-bounds read error and read contents of memory on the system or crash the affected application.
5) XML External Entity injection (CVE-ID: CVE-2018-20843)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input including XML names that contain a large number of colons. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
6) 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.
7) 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.
8) 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.
9) 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.
10) 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.
11) 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.
12) 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.
