Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2021-3541)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Resource management error (CVE-ID: CVE-2023-29469)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources when working with hashes of empty dict strings. A remote attacker can and perform a denial of service (DoS) attack.
3) NULL pointer dereference (CVE-ID: CVE-2023-28484)
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 xmlSchemaFixupComplexType. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
4) Integer overflow (CVE-ID: CVE-2022-40303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in parse.c when processing content when XML_PARSE_HUGE is set. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Resource management error (CVE-ID: CVE-2022-40304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption issues, such as double free errors and result in a denial of service.
6) NULL pointer dereference (CVE-ID: CVE-2021-3537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) 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.
8) Use-after-free (CVE-ID: CVE-2021-3518)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in libxml2. A remote attacker can use a specially crafted file and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Out-of-bounds write (CVE-ID: CVE-2021-3517)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the xml entity encoding functionality. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
10) Out-of-bounds read (CVE-ID: CVE-2020-24977)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the xmlEncodeEntitiesInternal() function in libxml2/entities.c in libxml2. A remote attacker can pas specially crafted XML data to the affected application, trigger out-of-bounds read error and read contents of memory on the system.
11) Integer overflow (CVE-ID: CVE-2022-23990)
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. 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-2022-22825)
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.
13) 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.
14) 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.
15) Input validation error (CVE-ID: CVE-2024-5462)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an unspecified error. A remote attacker on the local network can compromise the affected system.
16) Input validation error (CVE-ID: CVE-2024-5461)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due an unspecified vulnerability. A remote user on the local network can compromise the affected system.
