- Summary
- LibOSDP vulnerable to a null pointer deref in osdp_reply_name
- Details
-
Issue:
At ospdcommon.c, on the osdpreplyname function, any reply id between REPLYACK and REPLY_XRD is valid, but names array do not declare all of the range. On a case of an undefined reply id within the range, name will be null (
name = names[reply_id - REPLY_ACK];). Null name will casue a crash on next line:if (name[0] == '\0')as null[0] is invalid.Attack:
As this logic is not limited to a secure connection, attacker may trigger this vulnerability without any prior knowledge.
