LibOSDP vulnerable to a null pointer deref in osdp_reply_name
Quick fix
PYSEC-2026-1534 — libosdp: upgrade to the fixed version with the command below.
pip install --upgrade 'libosdp>=2.4.0'Details
### Issue: At ospd_common.c, on the osdp_reply_name function, any reply id between REPLY_ACK 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.
