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.
