>> PHP Multiple Buffer Overflow and Security Bypass Vulnerabilities
|
|
Multiple vulnerabilities have been identified in PHP, which could be exploited by attackers to bypass security restrictions, cause a denial of service or compromise a vulnerable web server.
The first issue is caused by a overflow in "memnstr()", which could be exploited by attackers to execute arbitrary code.
The second vulnerability is caused by an error in "imageloadfont" when handling invalid fonts, which could be exploited to cause a crash.
The third issue is caused by an error in the "curl" extension when handling "open_basedir" restrictions.
The fourth vulnerability is caused by an error in PCRE. For additional information, see : VUPEN/ADV-2008-2005
