Description
This security bulletin contains information about 5 vulnerabilities.
1) 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.
2) 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.
3) Protection mechanism failure (CVE-ID: CVE-2025-61731)
CWE-ID: CWE-693 - Protection Mechanism Failure
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-693 - Protection Mechanism Failure
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:A/AC:H/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Clear
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.
