CVE-2024-52296

Application crash via incomplete reply-name lookup

Published Nov 12, 2024 · Updated Nov 19, 2024

Null pointer dereference in goToMain LibOSDP before 2.4.0 allows physically proximate attackers to crash a consuming application. The osdp_reply_name function accepts every reply identifier from REPLY_ACK through REPLY_XRD, although its names table omits entries, then dereferences a null lookup result. A peer on the OSDP communication channel can send an undefined in-range reply without establishing a secure channel, terminating the process that embeds the library.
