Affected: Ubuntu:Pro:16.04:LTS: miniupnpd, Ubuntu:Pro:18.04:LTS: miniupnpd, Ubuntu:Pro:20.04:LTS: miniupnpd, Ubuntu:Pro:22.04:LTS: miniupnpd, Ubuntu:Pro:24.04:LTS: miniupnpd, Ubuntu:25.10: miniupnpd, Ubuntu:Pro:26.04:LTS: miniupnpd

miniupnpd contains an integer underflow vulnerability in SOAPAction header parsing that allows remote attackers to cause a denial of service or information disclosure by sending a malformed SOAPAction header with a single quote. Attackers can trigger an out-of-bounds memory read by exploiting improper length validation in ParseHttpHeaders(), where the parsed length underflows to a large unsigned value when passed to memchr(), causing the process to scan memory far beyond the allocated HTTP request buffer.
