Description Dhananjay Arunesh 2019-11-07 06:35:44 UTC 
A vulnerability was found in ReportLab through 3.5.26 allows remote code execution because of toColor(eval(arg)) in colors.py, as demonstrated by a crafted XML document with '<span color="' followed by arbitrary Python code.

Comment 1 Dhananjay Arunesh 2019-11-07 06:36:08 UTC 
Created python-reportlab tracking bugs for this issue:

Affects: fedora-all [bug 1769662]
Comment 7 Riccardo Schirone 2020-01-07 13:38:10 UTC 
Applications that use python-reportlab to generate PDFs and accept untrusted input that may be evaluated as a color for an element of the generated PDF, could be vulnerable to this flaw. It allows a possibly remote attacker to run any python code on the system.
