Description

This security bulletin contains information about 5 secuirty vulnerabilities.


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

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.


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

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. 


3) Protection mechanism failure (CVE-ID: CVE-2025-61731)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due CgoPkgConfig allows execution of pkg-config binary with flags that are not explicitly safe-listed. A remote attacker can trick the victim into executing arbitrary commands on the system.


4) Protection mechanism failure (CVE-ID: CVE-2025-68119)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to usage of unsafe options in Go toolchain. On systems with Mercurial installed (hg) downloading modules from non-standard sources can lead to unexpected code execution due to how external VCS are constructed. A remote attacker can trick the victim into downloading and executing arbitrary code on the target system.


5) Race condition (CVE-ID: CVE-2025-61730)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to a race condition when handling multiple messages during TLS 1.3 handshake. A remote attacker with ability to inject messages during the handshake can gain access to sensitive information.
