Debian DSA-125-1 : analog - XSS

Description

Yuji Takahashi discovered a bug in analog which allows a cross-site scripting type attack. It is easy for an attacker to insert arbitrary strings into any web server logfile. If these strings are then analysed by analog, they can appear in the report. By this means an attacker can introduce arbitrary JavaScript code, for example, into an analog report produced by someone else and read by a third person. Analog already attempted to encode unsafe characters to avoid this type of attack, but the conversion was incomplete.
