Description Karol Babioch 2019-03-12 12:26:12 UTC
CVE-2019-9637

Multiple security issues were found in PHP, a widely-used open source
general purpose scripting language: The EXIF extension had multiple cases
of invalid memory access and rename() was implemented insecurely.
For the stable distribution (stretch), this problem has been fixed in
version 7.0.33-0+deb9u3.
We recommend that you upgrade your php7.0 packages.
For the detailed security status of php7.0 please refer to
its security tracker page at:
\
https://security-tracker.debian.org/tracker/php7.0

15/php7, 12/php5, 11sp3/php53, 11/php5

Let /tmp be part of other device than $PWD.

$ cat test.php
<?php
  file_put_contents('oldfile', "hola\n");
  rename('oldfile', '/tmp/newfile');
?>
$ strace php test.php
[..]
rename("oldfile", "/tmp/newfile")       = -1 EXDEV (Invalid cross-device link)
[..]
openat(AT_FDCWD, "/128892/oldfile", O_RDONLY) = 3
[..]
openat(AT_FDCWD, "/tmp/newfile", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
[..]
chmod("/tmp/newfile", 0100644)          = 0
chown("/tmp/newfile", 0, 0)             = 0
unlink("oldfile")                       = 0
