The remote host is missing updates announced in
advisory RHSA-2005:032.
PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.
Flaws including possible information disclosure, double free, and negative
reference index array underflow were found in the deserialization code of
PHP. PHP applications may use the unserialize function on untrusted user
data, which could allow a remote attacker to gain access to memory or
potentially execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1019 to
this issue.
A flaw in the exif extension of PHP was found which lead to a stack
overflow. An attacker could create a carefully crafted image file in such
a way which, if parsed by a PHP script using the exif extension, could
cause a crash or potentially execute arbitrary code. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1065 to this issue.
Flaws were found in shmop_write, pack, and unpack PHP functions. These
functions are not normally passed user supplied data, so would require a
malicious PHP script to be exploited. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1018 to
this issue.
Users of PHP should upgrade to these updated packages, which contain fixes
for these issues.
