Debian: slrn buffer overflow

Bill Nottingham reported a problem in the wrapping/unwrapping functions of the slrn newsreader. A long header in a message might overflow a buffer and which could result into executing arbitraty code encoded in the message. The default configuration does not have wrapping enabled, but it can easily be enabled either by changing the configuration or pressing W while viewing a message. Fixed packages are available from security.debian.org.

Package        : slrn
Problem type   : buffer overflow
Debian-specific: no

Bill Nottingham reported a problem in the wrapping/unwrapping
functions of the slrn newsreader. A long header in a message
might overflow a buffer and which could result into executing
arbitraty code encoded in the message.

The default configuration does not have wrapping enable, but it
can easily be enabled either by changing the configuration or
pressing W while viewing a message.

This has been fixed in version 0.9.6.2-9potato1 and we recommand
that you upgrade your slrn package immediately.
