Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Memory leak (CVE-ID: CVE-2022-1012)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.
2) Input validation error (CVE-ID: CVE-2022-27664)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2022-30633)
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 when calling Unmarshal on a XML document into a Go struct which has a nested field that uses the any field tag. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Infinite loop (CVE-ID: CVE-2021-33194)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop. A remote attacker can pass crafted ParseFragment input to the application, consume all available system resources and cause denial of service conditions.
5) Race condition (CVE-ID: CVE-2022-1729)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within sys_perf_event_open() in Linux kernel. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
6) Use-after-free (CVE-ID: CVE-2022-32250)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free incorrect NFT_STATEFUL_EXPR in net/netfilter/nf_tables_api.c in Linux kernel. A local user with ability to create user/net namespaces can execute arbitrary code with root privileges.
7) Heap-based buffer overflow (CVE-ID: CVE-2022-27666)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c in Linux kernel. A local unprivileged user can pass specially crafted data to the system, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
8) Input validation error (CVE-ID: CVE-2022-35252)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an
HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.
9) Buffer Over-read (CVE-ID: CVE-2020-28915)
The vulnerability allows a local user with physical access to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds (OOB) memory access flaw in fbcon_get_font() function in drivers/video/fbdev/core/fbcon.c in fbcon driver module in the Linux kernel. A local user with special user privilege and with physical access can gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information.
