CVE reference:	CVE-2007-2027

Description: Arnaud Giersch has reported a weakness in ELinks, which potentially can be exploited by malicious, local users to gain escalated privileges. The weakness is caused due to the "add_filename_to_string()" function in src/intl/gettext/loadmsgcat.c reading gettext catalogs from potentially untrusted paths. This can be exploited to execute arbitrary code with escalated privileges by enticing another user to run ELinks in a specially prepared directory environment. Solution: Fixed in the GIT repository. http://pasky.or.cz/gitweb.cgi?p=elink...c564af3c12f40743b7e1adcfd3a034d73b601 http://pasky.or.cz/gitweb.cgi?p=elink...f364ba2803f98d71775dc03b694d6403c0754 Provided and/or discovered by: Arnaud Giersch Original Advisory: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=417789 http://pasky.or.cz/gitweb.cgi?p=elink...c564af3c12f40743b7e1adcfd3a034d73b601 http://pasky.or.cz/gitweb.cgi?p=elink...f364ba2803f98d71775dc03b694d6403c0754
