Bug ID: 57985
Summary: rsvg large stderr cause a PHP memory exhaustion
Product: MediaWiki
Version: unspecified

OS: All
Status: NEW
Severity: normal

I have spotted on the Wikimedia cluster a SVG image that cause RSVG to generate
roughly 125MB of stderr output.
In includes/media/SVG.php we log that error using something like:
wfDebugLog( 'thumbnails', trim($stderr) );
trim() thus returns a copy of $stderr (aka roughly 125MB) which can't be
allocated by PHP under its max memory constraint. That result in a fatal error
and no log at all.
Which should probably substr() the $stderr before handling it. No point in
logging the full error IMHO.
