CVE-2013-4248

Status Candidate

Overview

The openssl_x509_parse function in openssl.c in the OpenSSL module in PHP before 5.4.18 and 5.5.x before 5.5.2 does not properly handle a '�' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

Mandriva Linux Security Advisory 2014-014

Mandriva Linux Security Advisory 2014-014 - The openssl_x509_parse function in openssl.c in the OpenSSL module in PHP before 5.4.18 and 5.5.x before 5.5.2 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. The asn1_time_to_time_t function in ext/openssl/openssl.c in PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7 does not properly parse notAfter timestamps in X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service via a crafted certificate that is not properly handled by the openssl_x509_parse function. The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service via a crafted interval specification. The updated php packages have been upgraded to the 5.5.8 version which is not vulnerable to these issues. Additionally, the PECL packages which requires so has been rebuilt for php-5.5.8 and some has been upgraded to their latest versions.

Red Hat Security Advisory 2013-1615-02

Red Hat Security Advisory 2013-1615-02 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was found that PHP did not properly handle file names with a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. A flaw was found in PHP's SSL client's hostname identity check when handling certificates that contain hostnames with NULL bytes. If an attacker was able to get a carefully crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate to conduct man-in-the-middle attacks to spoof SSL servers.

Red Hat Security Advisory 2013-1307-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was found that PHP did not properly handle file names with a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. It was found that PHP did not check for carriage returns in HTTP headers, allowing intended HTTP response splitting protections to be bypassed. Depending on the web browser the victim is using, a remote attacker could use this flaw to perform HTTP response splitting attacks.

Debian Linux Security Advisory 2742-1 - It was discovered that PHP, a general-purpose scripting language commonly used for web application development, did not properly process embedded NUL characters in the subjectAltName extension of X.509 certificates. Depending on the application and with insufficient CA-level checks, this could be abused for impersonating other users.
