Description

This security bulletin contains information about 4 vulnerabilities.


1) Race condition (CVE-ID: CVE-2021-45710)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a race condition. A remote attacker can exploit the race and execute arbitrary code on the system.


2) Resource exhaustion (CVE-ID: CVE-2022-24713)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (ReDoS) attack.

The vulnerability exists due regex for Rust does not properly control consumption of internal resources when parsing untrusted input. A remote attacker can pass specially crafted data to the application and perform a regular expression denial of service (ReDoS) attack.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-31394)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform DoS attack.

The vulnerability exists due to the library does not allow customization of the max_header_list_size method in the H2 third-party software. A remote attacker can send overly large requests to the application and perform a denial of service (DoS) attack.


4) Code Injection (CVE-ID: CVE-2023-1521)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way the server handles compile request. A local user can execute arbitrary code with the privileges of a local sccache server by preloading the code in a shared library passed to LD_PRELOAD.
