Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) 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.
2) Infinite loop (CVE-ID: CVE-2025-62727)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop. A remote attacker can send a specially crafted HTTP Range header that triggers quadratic-time processing in Starlette's FileResponse Range parsing/merging logic and cause denial of service conditions.
3) 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.
4) 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.
5) Resource exhaustion (CVE-ID: CVE-2025-61729)
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.
6) Improper certificate validation (CVE-ID: CVE-2025-61727)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists in crypto/x509 due to incorrect handling of wildcard SANs in the leaf certificate when processing excluded constraint in a certificate chain. A remote attacker can create a specially crafted certificate and bypass implemented domain restrictions and perform MitM or phishing attacks.
7) Resource exhaustion (CVE-ID: CVE-2025-61724)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in net/textproto due to the Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. A remote attacker can trigger excessive CPU consumption and perform a denial of service (DoS) attack.
8) 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.
9) Improper Encoding or Escaping of Output (CVE-ID: CVE-2025-58189)
The vulnerability allows a remote attacker to perform spoofing attacks.
The vulnerability exists due to missing sanitization of input data when the Conn.Handshake fails during ALPN negotiation in crypto/tls. A remote attacker can pass specially crafted input via an error message and influence the application behavior, leading to a potential spoofing attack.
10) 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.
11) 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.
12) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-58186)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in net/http due to the application does not limit the number of cookies sent in the request. A remote attacker can send a lot of very small cookies such as "a=;" and cause large memory consumption.
13) Resource exhaustion (CVE-ID: CVE-2025-58185)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in encoding/asn1 due to application does not properly control consumption of internal resources when parsing DER payloads. A remote attacker can trigger memory exhaustion and perform a denial of service (DoS) attack.
14) Resource exhaustion (CVE-ID: CVE-2025-58183)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in archive/tar due to the tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A remote attacker can pass a specially crafted archive to the application and perform a denial of service (DoS) attack.
15) Input validation error (CVE-ID: CVE-2025-47912)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists in net/url due to the Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. A remote attacker can abuse such behavior to perform spoofing attacks.
