Vulnerabilities

A use-after-free vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 12.1.2.15332. By prematurely deleting objects associated with pages, a specially crafted PDF document can trigger the reuse of previously freed memory, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

<br /> All versions of GE Digital CIMPLICITY that are not adhering to SDG guidance and accepting documents from untrusted sources are vulnerable to memory corruption issues due to insufficient input validation, including issues such as out-of-bounds reads and writes, use-after-free, stack-based buffer overflows, uninitialized pointers, and a heap-based buffer overflow. Successful exploitation could allow an attacker to execute arbitrary code.<br /> <br />

A type confusion vulnerability exists in the Javascript checkThisBox method as implemented in Foxit Reader 12.1.2.15332. Specially crafted Javascript code inside a malicious PDF document can cause memory corruption and lead to remote code execution. User would need to open a malicious file to trigger the vulnerability.

A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15332 handles destroying annotations. Specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A use-after-free vulnerability exists in the JavaScript engine of Foxit Software&amp;#39;s PDF Reader, version 12.1.1.15289. A specially crafted PDF document can trigger the reuse of previously freed memory by manipulating form fields of a specific type. This can lead to memory corruption and arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

Issue summary: Checking excessively long DH keys or parameters may be very slow.<br /> <br /> Impact summary: Applications that use the functions DH_check(), DH_check_ex()<br /> or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long<br /> delays. Where the key or parameters that are being checked have been obtained<br /> from an untrusted source this may lead to a Denial of Service.<br /> <br /> The function DH_check() performs various checks on DH parameters. One of those<br /> checks confirms that the modulus (&amp;#39;p&amp;#39; parameter) is not too large. Trying to use<br /> a very large modulus is slow and OpenSSL will not normally use a modulus which<br /> is over 10,000 bits in length.<br /> <br /> However the DH_check() function checks numerous aspects of the key or parameters<br /> that have been supplied. Some of those checks use the supplied modulus value<br /> even if it has already been found to be too large.<br /> <br /> An application that calls DH_check() and supplies a key or parameters obtained<br /> from an untrusted source could be vulernable to a Denial of Service attack.<br /> <br /> The function DH_check() is itself called by a number of other OpenSSL functions.<br /> An application calling any of those other functions may similarly be affected.<br /> The other functions affected by this are DH_check_ex() and<br /> EVP_PKEY_param_check().<br /> <br /> Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications<br /> when using the &amp;#39;-check&amp;#39; option.<br /> <br /> The OpenSSL SSL/TLS implementation is not affected by this issue.<br /> The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

Deserialization of Untrusted Data vulnerability in Apache ShardingSphere-Agent, which allows attackers to execute arbitrary code by constructing a special YAML configuration file.<br /> <br /> The attacker needs to have permission to modify the ShardingSphere Agent YAML configuration file on the target machine, and the target machine can access the URL with the arbitrary code JAR.<br /> An attacker can use SnakeYAML to deserialize java.net.URLClassLoader and make it load a JAR from a specified URL, and then deserialize javax.script.ScriptEngineManager to load code using that ClassLoader. When the ShardingSphere JVM process starts and uses the ShardingSphere-Agent, the arbitrary code specified by the attacker will be executed during the deserialization of the YAML configuration file by the Agent.<br /> <br /> This issue affects ShardingSphere-Agent: through 5.3.2. This vulnerability is fixed in Apache ShardingSphere 5.4.0.
