Bug ID: 2010
Summary: sljitProtExecAllocator temp file descriptor isn't
CLOEXEC
Product: PCRE
Version: N/A
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: p...@hermes.cam.ac.uk
Reporter: c...@gnome.org
CC: pcre-dev@exim.org
Libraries that open files should make sure the FD is closed on exec, so either
open using O_CLOEXEC, or set FD_CLOEXEC on the FD later.
Here the (temp) file is opened using mkstemp(), so an fcntl(fd, F_SETFD,
FD_CLOEXEC) should be placed immediately afterwards.
