CVE-2026-115865

Starlet versions before 0.33 for Perl allow a request declaring a large Content-Length to kill a worker by exhausting memory. The request body is read in a loop that asks sysread for all of the remaining declared length at once. Perl grows the read buffer to that size before any data arrives, so a length larger than available memory makes the worker exit with an uncatchable out of memory error before the application is called. A remote attacker can force a worker restart with each request of a few bytes.

Template for a VuXML entry

Check the content

Check the version numbers before you commit this entry. Some ports share an entry in the CVE database with another port, such as sqlite2 and sqlite3. The version shown here may then be one that never existed for this port.

Ranges per package from the CVE rows that match this port, in pkg notation with the port's epoch and revision, every bound checked with pkg; one range per epoch the port actually had. make newentry in security/vuxml creates the vid.

No CPE in the port Makefile

www/p5-Starlet (CPE matched by the package name) has no USES=cpe. The CVE was matched through a CPE from another source, so the package and the version range may belong to a different product. Check the CVE record before using this entry.
