漏洞信息
The evince packages provide a simple multi-page document viewer for Portable Document Format (PDF), PostScript (PS), Encapsulated PostScript (EPS) files, and, with additional back-ends, also the Device Independent File format (DVI) files.
It was found that evince did not properly sanitize the command line which is run to untar Comic Book Tar (CBT) files, thereby allowing command injection. A specially crafted CBT file, when opened by evince or evince-thumbnailer, could execute arbitrary commands in the context of the evince program. (CVE-2017-1000083)
