VuXML IDDescription
66dbb2ee-99b8-45b2-bb3e-640caea67a60leafnode -- fetchnews denial-of-service triggered by transmission abort/timeout

When an upstream server aborts the transmission or stops sending data after the fetchnews program has requested an article header or body, fetchnews may crash, without querying further servers that are configured. This can prevent articles from being fetched.

a051a4ec-3aa1-4dd1-9bdc-a61eb5700153leafnode fetchnews denial-of-service triggered by truncated transmission

When a downloaded news article ends prematurely, i. e. when the server sends [CR]LF.[CR]LF before sending a blank line, fetchnews may wait indefinitely for data that never arrives. Workaround: configure "minlines=1" (or use a bigger value) in the configuration file. Found by Toni Viemerö.

b5ffaa2a-ee50-4498-af99-61bc1b163c00leafnode -- denial of service vulnerability

Matthias Andree reports:

A vulnerability was found in the fetchnews program (the NNTP client) that may under some circumstances cause a wait for input that never arrives, fetchnews "hangs". [...]

As only one fetchnews program can run at a time, subsequently started fetchnews and texpire programs will terminate. [...]

Upgrade your leafnode package to version 1.11.3.
