Description
A command injection issue exists in the
ev spawn() function within shell/ev-application.c. The software fails to apply g shell quote when building a command line from PDF link-destination fields, specifically within /GoToR actions. This allows an attacker to inject arguments, such as --gtk-module=PATH, by using spaces in the destination values. If a user is tricked into clicking a link in a malicious PDF, the application may load a polyglot file—a file that is simultaneously a valid PDF and a valid ELF shared library—via dlopen(). This results in arbitrary code execution as the user when the ELF constructor runs during initialization. The issue can be triggered through format strings like --page-label=%s, --named-dest=%s, and --find=%s.Recommendations
Update Atril to version 1.26.3 or 1.28.4.
Update Evince to version 48.4 or later.
Update Xreader to version 4.6.4 or 3.6.7.
At the moment, there is no information about a newer version that contains a fix for this vulnerability for Papers.
