Amazon Linux AMI : php (ALAS-2011-07)

Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

The MITRE CVE database describes these CVEs as :

Revert is_a() behavior to php <= 5.3.6 and add a new new option
(allow_string) for the new behavior (accept string and raise autoload
if needed)

Use-after-free vulnerability in the substr_replace function in PHP
5.3.6 and earlier allows context-dependent attackers to cause a denial
of service (memory corruption) or possibly have unspecified other
impact by using the same variable for multiple arguments.

Stack-based buffer overflow in the socket_connect function in
ext/sockets/sockets.c in PHP 5.3.3 through 5.3.6 might allow
context-dependent attackers to execute arbitrary code via a long
pathname for a UNIX socket.

The rfc1867_post_handler function in main/rfc1867.c in PHP before
5.3.7 does not properly restrict filenames in multipart/form-data POST
requests, which allows remote attackers to conduct absolute path
traversal attacks, and possibly create or overwrite arbitrary files,
via a crafted upload request, related to a 'file path injection

crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain
platforms, does not properly handle 8-bit characters, which makes it
easier for context-dependent attackers to determine a cleartext
password by leveraging knowledge of a password hash.

PHP before 5.3.7 does not properly check the return values of the
malloc, calloc, and realloc library functions, which allows
context-dependent attackers to cause a denial of service (NULL pointer
dereference and application crash) or trigger a buffer overflow by
leveraging the ability to provide an arbitrary value for a function
argument, related to (1) ext/curl/interface.c, (2)
ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4)
ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6)
ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8)
ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10)
TSRM/tsrm_win32.c, and (11) the strtotime function.
