New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote Fedora Core host is missing a security update.
DescriptionThis update fixes a number of security issues in PHP :
- various integer overflow flaws were found in the PHP gd extension. A script that could be forced to resize images from an untrusted source could possibly allow a remote attacker to execute arbitrary code as the apache user. (CVE-2007-3996)
- an integer overflow flaw was found in the PHP chunk_split function. If a remote attacker was able to pass arbitrary data to the third argument of chunk_split they could possibly execute arbitrary code as the apache user. Note that it is unusual for a PHP script to use the chunk_script function with a user-supplied third argument. (CVE-2007-2872)
- a previous security update introduced a bug into PHP session cookie handling. This could allow an attacker to stop a victim from viewing a vulnerable website if the victim has first visited a malicious web page under the control of the attacker, and that page can set a cookie for the vulnerable website. (CVE-2007-4670)
- a flaw was found in the PHP money_format function. If a remote attacker was able to pass arbitrary data to the money_format function this could possibly result in an information leak or denial of service. Note that is is unusual for a PHP script to pass user-supplied data to the money_format function. (CVE-2007-4658)
- a flaw was found in the PHP wordwrap function. If a remote attacker was able to pass arbitrary data to the wordwrap function this could possibly result in a denial of service. (CVE-2007-3998)
- a bug was found in PHP session cookie handling. This could allow an attacker to create a cross-site cookie insertion attack if a victim follows an untrusted carefully-crafted URL. (CVE-2007-3799)
- an infinite-loop flaw was discovered in the PHP gd extension. A script that could be forced to process PNG images from an untrusted source could allow a remote attacker to cause a denial of service. (CVE-2007-2756)
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
