Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) 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.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-23916)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect implementation of the "chained" HTTP compression algorithms, where the number of links in the decompression chain was limited for each header instead of the entire request. A remote attacker can send a specially crafted compressed HTTP request with numerous headers and perform a denial of service (DoS) attack.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-48303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the from_header() function in list.c when handling V7 archives. A remote attacker can trick the victim to open a specially crafted V7 archive, trigger a heap-based buffer 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-2022-47629)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the CRL signature parser. 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 exhaustion (CVE-ID: CVE-2022-45061)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to usage of an unnecessary quadratic algorithm in one path when processing some inputs to the IDNA (RFC 3490) decoder. A remote attacker can pass a specially crafted name to he decoder, trigger resource excessive CPU consumption and perform a denial of service (DoS) attack.
6) Use-after-free (CVE-ID: CVE-2022-43680)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2022-42012)
The vulnerability allows a local user to escalate privileges on the system.
8) 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.
9) Incorrect Regular Expression (CVE-ID: CVE-2022-40897)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing HTML content. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
10) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
11) 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.
12) 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.
13) 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.
14) Improper Privilege Management (CVE-ID: CVE-2022-4415)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper privilege management when handling coredumps in coredump/coredump.c. A local user can gain access to sensitive information.
The vulnerability affects systems with libacl support.
15) Off-by-one (CVE-ID: CVE-2021-46848)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an ETYPE_OK off-by-one error in asn1_encode_simple_der in Libtasn1. A remote attacker can pass specially crafted data to the application, trigger an off-by-one error and perform a denial of service (DoS) attack.
16) Open redirect (CVE-ID: CVE-2021-28861)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in lib/http/server.py due to missing protection against multiple (/) at the beginning of URI path. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
17) Type conversion (CVE-ID: CVE-2020-10735)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion in algorithms with quadratic time complexity when using non-binary bases within the int() call. A remote attacker can pass specially crafted data to the affected application and perform a denial of service (DoS) attack.
