Acrobat Reader versions 24.002.21005, 24.001.30159, 20.005.30655, 24.003.20054 and earlier are affected by a Type Confusion vulnerability that could result in arbitrary code execution in the context of the current user. This issue occurs when a resource is accessed using a type that is not compatible with the actual object type, leading to a logic error that an attacker could exploit. Exploitation of this issue requires user interaction in that a victim must open a malicious file.Show less

Issue 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.Show less
