Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Out-of-bounds read (CVE-ID: CVE-2022-2873)
The vulnerability allows a local user to crash the kernel.
The vulnerability exists due to a boundary condition within the Intel iSMT SMBus host controller driver. A local user can send specially crafted data to the I2C_SMBUS IOCTL, trigger an out-of-bounds read error and crash the system.
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) 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.
7) Use-after-free (CVE-ID: CVE-2022-41222)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a use-after-free error caused by a stale TLB in mm/mremap.c, because an rmap lock is not held during a PUD move. A local user can gain access to sensitive information.
8) Buffer overflow (CVE-ID: CVE-2022-43945)
The vulnerability allows a remote attacker to perform a denial of service attacl.
The vulnerability exists due to a boundary error within the Linux kernel NFSD implementation. A remote attacker can send the RPC message over TCP with garbage data added at the end of the message, trigger memory corruption and perform a denial of service (DoS) attack.
9) 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.
10) 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.
