CVE-2015-8107 [HIGH] CVE-2015-8107 a2ps: output_file() format string flaw
CVE-2015-8107 a2ps: output_file() format string flaw
A flaw was found in a2sp:
When a user runs a2ps with malicious crafted pro(a2ps prologue) file, an attacker can execute arbitrary code. The function output_file processes the %Expand command in pro file. The variable `expansion' in the function output_file may hold a malicious input string, which can be used as a format argument of vsprintf.
No upstream patch is available at this moment.
