CWE-843
AllowedAccess of Resource Using Incompatible Type ('Type Confusion')
Abstraction: Base · Status: Incomplete
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
1126 vulnerabilities reference this CWE, most recent first.
GHSA-79R8-2QH7-XQP4
Vulnerability from github – Published: 2023-11-27 18:31 – Updated: 2025-11-04 21:30A type confusion vulnerability exists in the way Foxit Reader 12.1.2.15356 handles field value properties. A specially crafted Javascript code inside a malicious PDF document can trigger this vulnerability, 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.

GHSA-7M4M-PWHV-49C5
Vulnerability from github – Published: 2024-09-03 18:31 – Updated: 2026-05-12 12:32Issue summary: Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address resulting in abnormal termination of the application process.
Impact summary: Abnormal termination of an application can a cause a denial of service.
Applications performing certificate name checks (e.g., TLS clients checking
server certificates) may attempt to read an invalid memory address when
comparing the expected name with an otherName subject alternative name of an
X.509 certificate. This may result in an exception that terminates the
application program.
Note that basic certificate chain validation (signatures, dates, ...) is not affected, the denial of service can occur only when the application also specifies an expected DNS name, Email address or IP address.
TLS servers rarely solicit client certificates, and even when they do, they generally don't perform a name check against a reference identifier (expected identity), but rather extract the presented identity after checking the certificate chain. So TLS servers are generally not affected and the severity of the issue is Moderate.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
