CVE-2012-2386

Status Candidate

Overview

Integer overflow in the phar_parse_tarfile function in tar.c in the phar extension in PHP before 5.3.14 and 5.4.x before 5.4.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted tar file that triggers a heap-based buffer overflow.

Red Hat Security Advisory 2012-1046-01

Red Hat Security Advisory 2012-1046-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was discovered that the PHP XSL extension did not restrict the file writing capability of libxslt. A remote attacker could use this flaw to create or overwrite an arbitrary file that is writable by the user running PHP, if a PHP script processed untrusted eXtensible Style Sheet Language Transformations content. Note: This update disables file writing by default. A new PHP configuration directive, "xsl.security_prefs", can be used to enable file writing in XSLT.

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1481-1 - It was discovered that PHP incorrectly handled certain Tidy::diagnose operations on invalid objects. A remote attacker could use this flaw to cause PHP to crash, leading to a denial of service. It was discovered that PHP incorrectly handled certain multi-file upload filenames. A remote attacker could use this flaw to cause a denial of service, or to perform a directory traversal attack. Rubin Xu and Joseph Bonneau discovered that PHP incorrectly handled certain Unicode characters in passwords passed to the crypt() function. A remote attacker could possibly use this flaw to bypass authentication. Various other issues were also addressed.

Mandriva Linux Security Advisory 2012-093
Posted Jun 16, 2012
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2012-093 - There is a programming error in the DES implementation used in crypt() in ext/standard/crypt_freesec.c when handling input which contains characters that can not be represented with 7-bit ASCII. When the input contains characters with only the most significant bit set (0x80), that character and all characters after it will be ignored. An integer overflow, leading to heap-based buffer overflow was found in the way Phar extension of the PHP scripting language processed certain fields by manipulating TAR files. A remote attacker could provide a specially-crafted TAR archive file, which once processed in an PHP application using the Phar extension could lead to denial of service , or, potentially arbitrary code execution with the privileges of the user running the application. The updated php packages have been upgraded to the 5.3.14 version which is not vulnerable to these issues.
