Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Denial of service (CVE-ID: CVE-2014-0237)

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

The vulnerability exists in cdf_unpack_summary_info function in cdf.c in the Fileinfo component in PHP before 5.4.29 and 5.5.x before 5.5.13 due to performance degradation. A remote attacker can trigger many file_printf calls and cause the service to crash.

2) Infinite loop (CVE-ID: CVE-2014-0238)

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

The vulnerability exists due to infinite loop in the cdf_read_property_info function in cdf.c in the Fileinfo component in PHP before 5.4.29 and 5.5.x before 5.5.13. A remote attacker can trigger out-of-bounds memory access via a vector that (1) has zero length or (2) is too long and cause the service to crash.

3) NULL pointer dereference (CVE-ID: CVE-2014-2497)

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted color table in an XPM file.

4) Heap-based buffer overflow (CVE-ID: CVE-2014-4049)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to heap-based buffer overflow in the php_parserr function in ext/standard/dns.c. A remote attacker can trigger memory corruption via a crafted DNS TXT record, related to the dns_get_record function and cause the service to crash or execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
