Description
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2024-40635)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/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 integer overflow when handling a UID:GID larger than the maximum 32-bit signed integer. A local user can pass a large user identifier value to the application, trigger an integer overflow and execute arbitrary code on the target system.
2) Input validation error (CVE-ID: CVE-2025-22870)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to
"[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially gain access to sensitive information or functionality.
3) Resource exhaustion (CVE-ID: CVE-2025-27144)
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 (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing JWS and JWE input. A remote attacker can pass specially crafted data to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
