CVE-2019-5275

Name of the Vulnerable Software and Affected Versions USG9500 versions V500R001C30 through V500R001C60

Description The issue is related to a flaw in the X.509 implementation, which can cause a heap buffer overflow when decoding a certificate. This can be exploited by an attacker using a malicious certificate to perform a denial of service attack on the affected products.

Recommendations For USG9500 versions V500R001C30 through V500R001C60, consider restricting the use of the X.509 implementation until a patch is available. As a temporary workaround, avoid using certificates that may trigger the heap buffer overflow in the affected products.
