5) Out-of-bounds read (CVE-ID: CVE-2022-42011)
The vulnerability allows a local user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error caused by an invalid array of fixed-length elements where the length of the array is not a multiple of the length of the element. A local user can trigger an out-of-bounds read and gain access to sensitive information.
6) Reachable Assertion (CVE-ID: CVE-2022-42010)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion in debug builds caused by a syntactically invalid type signature with incorrectly nested parentheses and curly brackets. A local user can perform a denial of service (DoS) attack.
7) 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.
8) 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.
9) Improper Validation of Array Index (CVE-ID: CVE-2022-35737)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when handling an overly large input passed as argument to a C API. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
10) Predictable from Observable State (CVE-ID: CVE-2022-30699)
The vulnerability allows a remote attacker to poison DNS cache.
The vulnerability exists due to the way Unbound handles delegation information expiration event. A remote attacker who controls a rouge DNS server can force the Unbound instance to cache incorrect information about domain delegation and permanently poison the DNS cache, e.g. perform the "ghost domain names" attack.
The attack is perform when Unbound is queried for a rogue domain name, which cached delegation information is about to expire. The rogue nameserver delays the response until the cached delegation information expires. Upon receiving the delayed answer containing the delegation information, Unbound overwrites the now expired entries.
11) Predictable from Observable State (CVE-ID: CVE-2022-30698)
The vulnerability allows a remote attacker to poison DNS cache.
The vulnerability exists due to the way Unbound handles delegation information expiration event. A remote attacker who controls a rouge DNS server can force the Unbound instance to cache incorrect information about subdomain delegation and permanently poison the DNS cache, e.g. perform the "ghost domain names" attack.
The attack is carried out when Unbound is queried for a subdomain of a rogue domain name. The rogue nameserver returns delegation information for the subdomain that updates Unbound's delegation cache. This action can be repeated before expiry of the delegation information by querying Unbound for a second level subdomain which the rogue nameserver provides new delegation information. Since Unbound is a child-centric resolver, the ever-updating child delegation information can keep a rogue domain name resolvable long after revocation.12) Heap-based buffer overflow (CVE-ID: CVE-2022-30293)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the WebCore::TextureMapperLayer::setContentsLayer() function in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp. A remote attacker can trick the victim into visiting a specially crafted web page, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
