CVE-2003-0166
HighSummary
Integer signedness error in the emalloc() function for PHP before version 4.3.2 allows remote attackers to cause a denial of service (memory consumption) and possibly execute arbitrary code via negative arguments to functions such as socket_recv and socket_recvfrom.
Risk Assessment
The organization may be exposed to attacks that lead to denial of service and potential execution of malicious code, which could result in data loss or system compromise.
Recommendation
It is recommended to upgrade PHP to version 4.3.2 or later to mitigate this vulnerability and to monitor systems for unauthorized activities.
