Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2025-24970)

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 in SslHandler when using native SSLEngine. A remote attacker can send a specially crafted packet to the application and perform a denial of service (DoS) attack.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-22871)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when handling chunked data in net/http. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


3) Resource exhaustion (CVE-ID: CVE-2025-61725)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the ParseAddress function in net/mail does not properly control consumption of internal resources. A remote attacker can compose a specially crafted email message that triggers excessive CPU consumption leading to denial of service. 


4) Resource exhaustion (CVE-ID: CVE-2025-61723)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in encoding/pem due to application does not properly control consumption of internal resources when parsing untrusted PEM input. A remote attacker can trigger CPU exhaustion and perform a denial of service (DoS) attack.


5) Input validation error (CVE-ID: CVE-2025-58188)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in crypto/x509 due to an error when validating certificate chains which contain DSA public keys. A remote attacker can pass a specially crafted certificate to the application and crash it.


6) Resource exhaustion (CVE-ID: CVE-2025-58187)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to quadratic complexity when checking name constraints in crypto/x509. A remote attacker can pass a specially crafted x509 certificate to the application and trigger resource exhaustion. 


7) Race condition (CVE-ID: CVE-2025-47907)

The vulnerability allows an attacker to tamper with the application. 

The vulnerability exists due to a race condition when canceling a DB query. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system. A remote user can overwrite the expected results with those of another query, causing the call to Scan to return either unexpected results from the other query or an error.


8) OS Command Injection (CVE-ID: CVE-2025-4674)

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation when handling multiple VCS configuration metadata in Go toolchain. A remote attacker can trick the victim into directly cloning specially crafted Git or Mercurial repositories and execute arbitrary OS commands on the system.


9) Protection Mechanism Failure (CVE-ID: CVE-2025-22874)

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

The vulnerability exists due to an error in crypto/x509 when using ExtKeyUsageAny. When calling Verify with a VerifyOptions.KeyUsages that contains ExtKeyUsageAny it disables policy validation.

This only affected certificate chains which contain policy graphs, which are rather uncommon.


10) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-58056)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP/1.1 requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


11) Resource exhaustion (CVE-ID: CVE-2025-58057)

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 in BrotliDecoder and some other decompressing decoders. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
