04.06.2024, 10:15

A vulnerability regarding buffer copy without checking the size of input ('Classic Buffer Overflow') has been found in the login component. This allows remote attackers to write specific files containing non-sensitive information and conduct limited denial-of-service attacks via unspecified vectors. This attack only affects the login service which will automatically restart. The following models with Synology Camera Firmware versions before 1.1.1-0383 may be affected: BC500 and TC500.
