Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2023-2253)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. A remote attacker can send specially crafted requests to the "/v2/_catalog" API endpoint and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2023-39325)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2023-44487)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
4) 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.
5) NULL pointer dereference (CVE-ID: CVE-2023-2177)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the net/sctp/stream_sched.c in Linux kernel. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2023-3341)
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 handling control channel messages . A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2023-3609)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the the Linux kernel net/sched: cls_u32 component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
8) Use-after-free (CVE-ID: CVE-2023-3776)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the the Linux kernel's net/sched: cls_fw component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
9) Buffer overflow (CVE-ID: CVE-2023-4911)
The vulnerability allows a local user to escalate privileges on the system.
10) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-40217)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error in ssl.SSLSocket implementation when handling TLS client authentication. A remote attacker can trick the application to send data unencrypted.
