Bug ID: 15546
Summary: real_fopen does not set CLOEXEC in thread-safe way
Product: binutils
Version: unspecified
Status: NEW
Severity: minor
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: tromey at redhat dot com
Right now, bfdio.c:real_fopen sets the CLOEXEC flag on
any files it opens. Howevere, there is a window
between opening the file and setting this flag, during
which another thread could fork and exec.
The best fix would be to use O_CLOEXEC, or the fopen "e"
modifier, on platforms that support it.
