Description

This security bulletin contains information about 12 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2011-1464)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Buffer overflow in the strval function in PHP before 5.3.6, when the precision configuration option has a large value, might allow context-dependent attackers to cause a denial of service (application crash) via a small numerical value in the argument.


2) Input validation error (CVE-ID: CVE-2011-1466)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Integer overflow in the SdnToJulian function in the Calendar extension in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (application crash) via a large integer in the first argument to the cal_from_jd function.


3) Input validation error (CVE-ID: CVE-2011-1467)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Unspecified vulnerability in the NumberFormatter::setSymbol (aka numfmt_set_symbol) function in the Intl extension in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (application crash) via an invalid argument, a related issue to CVE-2010-4409.


4) Resource management error (CVE-ID: CVE-2011-1468)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple memory leaks in the OpenSSL extension in PHP before 5.3.6 might allow remote attackers to cause a denial of service (memory consumption) via (1) plaintext data to the openssl_encrypt function or (2) ciphertext data to the openssl_decrypt function.


5) Input validation error (CVE-ID: CVE-2011-1469)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Unspecified vulnerability in the Streams component in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (application crash) by accessing an ftp:// URL during use of an HTTP proxy with the FTP wrapper.


6) Input validation error (CVE-ID: CVE-2011-1470)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The Zip extension in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (application crash) via a ziparchive stream that is not properly handled by the stream_get_contents function.


7) Input validation error (CVE-ID: CVE-2011-1471)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Integer signedness error in zip_stream.c in the Zip extension in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (CPU consumption) via a malformed archive file that triggers errors in zip_fread function calls.


8) Input validation error (CVE-ID: CVE-2011-0421)

The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference) via an empty ZIP archive that is processed with a (1) locateName or (2) statName operation.


9) Out-of-bounds read (CVE-ID: CVE-2011-0708)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in exif.c in the Exif extension in PHP before 5.3.6 on 64-bit platforms performs an incorrect cast, which. A remote attacker can perform a denial of service (application crash) via an image with a crafted Image File Directory (IFD) that triggers a buffer over-read.


10) Format string error (CVE-ID: CVE-2011-1153)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple format string vulnerabilities in phar_object.c in the phar extension in PHP 5.3.5 and earlier allow context-dependent attackers to obtain sensitive information from process memory, cause a denial of service (memory corruption), or possibly execute arbitrary code via format string specifiers in an argument to a class method, leading to an incorrect zend_throw_exception_ex call.


11) Input validation error (CVE-ID: CVE-2011-1092)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Integer overflow in ext/shmop/shmop.c in PHP before 5.3.6 allows context-dependent attackers to cause a denial of service (crash) and possibly read sensitive memory via a large third argument to the shmop_read function.


12) Input validation error (CVE-ID: CVE-2010-4645)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

strtod.c, as used in the zend_strtod function in PHP 5.2 before 5.2.17 and 5.3 before 5.3.5, and other products, allows context-dependent attackers to cause a denial of service (infinite loop) via a certain floating-point value in scientific notation, which is not properly handled in x87 FPU registers, as demonstrated using 2.2250738585072011e-308.
