CVE-2012-2451

Publication date 27 June 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The Config::IniFiles module before 2.71 for Perl creates temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack. NOTE: some of these details are obtained from third party information. NOTE: it has been reported that this might only be exploitable by writing in the same directory as the .ini file. If this is the case, then this issue might not cross privilege boundaries.

Notes

jdstrand

file is created in the same directory as the original file and so yama won't protect against it since this doesn't have to occur in a sticky directory. Typically would not cross privilege boundaries, but is a useful hardening measure in all cases.
