Description

This security bulletin contains information about 3 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2025-61729)

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 within the HostnameError.Error() function in crypto/x509 when printing error string for host certificate validation. A remote attacker can supply a specially crafted certificate to the application and trigger resource exhaustion, leading to a denial of service condition. 


2) Input validation error (CVE-ID: CVE-2025-61728)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/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 insufficient validation of user-supplied input when parsing zip archives. A remote attacker can pass specially crafted zip archive to the application and perform a denial of service (DoS) attack.


3) Resource exhaustion (CVE-ID: CVE-2025-61726)

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 within the Request.ParseForm method in net/http when parsing a URL-encoded form. A remote attacker can pass an overly large request with a large number of key-value pairs and consume all available memory on the system.
