Description Adam Mariš 2015-08-14 13:19:43 UTC

Florian Weimer reported that bug 1253692 is fixed only partially.
fscaps are not considered on GNU/Linux, and a check like getuid() == geteuid() misses cases where the program has switched UIDs completely.

CVE request:
https://bugzilla.mozilla.org/show_bug.cgi?id=1194678
