Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2022-2309)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the iterwalk() function. A remote attacker can pass specially crafted XML data to the application and perform a denial of service (DoS) attack.
2) 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.
3) 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.
