Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2024-35221)

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 reading the Manifest of Gem files when using Gem::Specification.from_yaml. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2024-47220)

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

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request containing both a Content-Length header and a Transfer-Encoding header 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) Inefficient regular expression complexity (CVE-ID: CVE-2024-49761)

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

The vulnerability exists due to insufficient input validation when parsing an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


4) Resource exhaustion (CVE-ID: CVE-2025-24294)

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 when handling DNS packets. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Input validation error (CVE-ID: CVE-2025-27219)

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 CGI::Cookie.parse. A remote attacker can send a specially crafted HTTP request to the application and perform a denial of service (DoS) attack.


6) Inefficient regular expression complexity (CVE-ID: CVE-2025-27220)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions in CGI::Util#escapeElement. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


7) Information disclosure (CVE-ID: CVE-2025-27221)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to URI#join, URI#merge, and URI#+ methods retain sensitive information, such as user:password, even after the host is replaced. A remote attacker can gain access to sensitive information.


8) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-6442)

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

The vulnerability exists due to improper validation of HTTP requests within the read_header() method. 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.
