![]() Typically an application will call this function twice. In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). It can be triggered via the stack_copy function.Įncoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence. Mruby through 2.1.2-rc has a heap-based buffer overflow in the mrb_yield_with_class function in vm.c because of incorrect VM stack handling. Libpng before 1.6.32 does not properly check the length of chunks against the user limit. The init_copy function in kernel.c in mruby 1.4.1 makes initialize_copy calls for TT_ICLASS objects, which allows attackers to cause a denial of service (mrb_hash_keys uninitialized pointer and application crash) or possibly have unspecified other impact. An attacker that can cause Ruby code to be run can use this to possibly execute arbitrary code. In versions of mruby up to and including 1.4.0, an integer overflow exists in src/vm.c::mrb_vm_exec() when handling OP_GETUPVAR in the presence of deep scope nesting, resulting in a use-after-free. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. From log4j 2.15.0, this behavior has been disabled by default. ![]() An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. ![]() You can subscribe to our Security Alerts to be notified when new Security Advisories are posted by following the guidance here, or by following the directions in the Security Alerts section on the Security Advisories and Notices page.Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints.
