php5 was updated to fix four security issues.
These security issues were fixed:
- CVE-2015-0231: Use-after-free vulnerability in the process_nested_data
function in ext/standard/var_unserializer.re in PHP before 5.4.37, 5.5.x
before 5.5.21, and 5.6.x before 5.6.5 allowed remote attackers to
execute arbitrary code via a crafted unserialize call that leverages
improper handling of duplicate numerical keys within the serialized
properties of an object. NOTE: this vulnerability exists because of an
incomplete fix for CVE-2014-8142 (bnc#910659).
- CVE-2014-9427: sapi/cgi/cgi_main.c in the CGI component in PHP through
5.4.36, 5.5.x through 5.5.20, and 5.6.x through 5.6.4, when mmap is used
to read a .php file, did not properly consider the mapping’s length
during processing of an invalid file that begins with a # character and
lacks a newline character, which caused an out-of-bounds read and might
(1) allow remote attackers to obtain sensitive information from php-cgi
process memory by leveraging the ability to upload a .php file or (2)
trigger unexpected code execution if a valid PHP script is present in
memory locations adjacent to the mapping (bnc#911664).
- CVE-2015-0232: The exif_process_unicode function in ext/exif/exif.c in
PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allowed
remote attackers to execute arbitrary code or cause a denial of service
(uninitialized pointer free and application crash) via crafted EXIF data
in a JPEG image (bnc#914690).
- CVE-2014-8142: Use-after-free vulnerability in the process_nested_data
function in ext/standard/var_unserializer.re in PHP before 5.4.36, 5.5.x
before 5.5.20, and 5.6.x before 5.6.4 allowed remote attackers to
execute arbitrary code via a crafted unserialize call that leverages
improper handling of duplicate keys within the serialized properties of
an object, a different vulnerability than CVE-2004-1019 (bnc#910659).
Additionally a fix was included that protects against a possible NULL
pointer use (bnc#910659).
This non-security issue was fixed:
- php53 ignored default_socket_timeout on outgoing SSL connection
(bnc#907519).
