Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: N/A)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 6 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an unauthenticated network-adjacent attacker to crash a PUPnP control-point application through heap use-after-free.

The vulnerability exists due to queued SSDP search-result callbacks retaining application cookies after client unregistration or search timeout, when applications may free them. An unauthenticated network-adjacent attacker can observe an outstanding search and flood matching replies during callback delays, causing queued callbacks to access cookies freed by the application.
