| CVE-2025-43857 | 1 Ruby-lang | 1 Net\ | 2025-05-12 | N/A | 7.5 HIGH |
| Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5, there is a possibility for denial of service by memory exhaustion when net-imap reads server responses. At any time while the client is connected, a malicious server can send can send a "literal" byte count, which is automatically read by the client's receiver thread. The response reader immediately allocates memory for the number of bytes indicated by the server response. This should not be an issue when securely connecting to trusted IMAP servers that are well-behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example, connecting to a user supplied hostname). This issue has been patched in versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5. | |||||
| CVE-2016-2339 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| An exploitable heap overflow vulnerability exists in the Fiddle::Function.new "initialize" function functionality of Ruby. In Fiddle::Function.new "initialize" heap buffer "arg_types" allocation is made based on args array length. Specially constructed object passed as element of args array can increase this array size after mentioned allocation and cause heap overflow. | |||||
| CVE-2016-2336 | 1 Ruby-lang | 1 Ruby | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| Type confusion exists in two methods of Ruby's WIN32OLE class, ole_invoke and ole_query_interface. Attacker passing different type of object than this assumed by developers can cause arbitrary code execution. | |||||
