Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2022-2879)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to absent limits on the maximum size of file headers within the Reader.Read method in archive/tar. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2022-41715)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in regexp/syntax when handling regular expressions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
