Bug Description
Environment:
Description: Ubuntu 12.04 LTS
Release: 12.04
libjpeg-turbo8 1.1.90+
Ubuntu's own patch (FixLibraryStar
The patch adds some auxv related stuff to the library init that attempt to read /proc/self/auxv. If it fails the above error is printed usually ending up to application's log that's using the library. Looking at the log it's completely unclear where that error came from and what file was it trying to read.
The /proc/self/auxv has 0400 permissions and is owned by the user who started the process. If the process drops privileges and setuid()'s to another user, the file is no longer readable.
