miniupnpd -- Integer underflow in SOAPAction header parsing

· CVE-2026-5720 · VuXML entry

An integer underflow in the SOAPAction header parsing in ParseHttpHeaders() lets a remote attacker trigger an out-of-bounds read by sending a malformed SOAPAction header containing a single quote. This can crash miniupnpd or disclose memory beyond the HTTP request buffer.

Affected versions

By system

0 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
