were incomplete, which caused crashes in certain situations with
Ubuntu 7.10. This update fixes the problem.
We apologize for the inconvenience.
It was discovered that the wordwrap function did not correctly check
lengths. Remote attackers could exploit this to cause a crash or
monopolize CPU resources, resulting in a denial of service.
Integer overflows were discovered in the strspn and strcspn
functions. Attackers could exploit this to read arbitrary
areas of memory, possibly gaining access to sensitive
Stanislav Malyshev discovered that money_format function did

send a specially crafted message and execute arbitrary code
with application privileges. (CVE-2007-4662)

privileges. (CVE-2007-2872, CVE-2007-4660, CVE-2007-4661)
Stefan Esser discovered that deeply nested arrays could be
made to fill stack space. A remote attacker could exploit

in a denial of service. (CVE-2007-1285, CVE-2007-4670)
Rasmus Lerdorf discovered that the htmlentities and
htmlspecialchars functions did not correctly stop when
handling partial multibyte sequences. A remote attacker
could exploit this to read certain areas of memory, possibly
gaining access to sensitive information. (CVE-2007-5898)
