CVE-2020-5249

A flaw was discovered in rubygem-puma, where it did not properly forbid untrusted input in an early-hints header. This flaw allows an attacker with the ability to tamper with HTTP headers to insert a carriage return character to end the header and then insert malicious content, allowing an HTTP...

CVE-2020-5247

A flaw was discovered in rubygem-puma, where it did not properly forbid untrusted input in a response header. This flaw allows an attacker with the ability to tamper with HTTP headers to insert a new-line and insert malicious content, allowing an HTTP response splitting, which exposes the risk of...

PyYAML: Arbitrary code execution

Background PyYAML is a YAML parser and emitter for Python. Description It was found that using yaml.load API on untrusted input could lead to arbitrary code execution. Impact A remote attacker could entice a user to process specially crafted input in an application using yaml.load from PyYAML,...

DEBIAN-CVE-2020-1953

Apache Commons Configuration uses a third-party library to parse YAML files which by default allows the instantiation of classes if the YAML includes special statements. Apache Commons Configuration versions 2.2, 2.3, 2.4, 2.5, 2.6 did not change the default settings of this library. So if a YAML...

Regular Expression Denial Of Service (ReDoS)

acorn is vulnerable to denial of service. A regex in the form of /x-\ud800/u causes the parser to enter an infinite loop as the string is not valid UTF-16 character. This results in it being sanitized before reaching the parser and when an application processes untrusted input and passes it...

PyYAML Input Validation Error Vulnerability

PyYAML is a Python based YAML parser and generator . There is an input validation error vulnerability in PyYAML, when the user loads a yaml file that the program does not trust through the fullload method or Fullloader method, it is easy to cause arbitrary code execution vulnerability, which can ...
