The update for munin issued as DSA-3794-2 caused a regression leading to Perl warnings being appended to the munin-cgi-graph log file. Updated packages are now available to correct this issue. For reference, the original advisory text follows. Stevie Trujillo discovered a local file write vulnerability in munin, a network-wide graphing framework, when CGI graphs are enabled. GET parameters are not properly handled, allowing to inject options into munin-cgi-graph and overwriting any file accessible by the user running the cgi-process.
