CVE-2007-4639 EXPLOIT
6.5
MEDIUM · CVSS 2.0 · EPSS 5.1% (pctl 92)
Patch early
A public exploit exists.
Description
EnterpriseDB Advanced Server 8.2 does not properly handle certain debugging function calls that occur before a call to pldbg_create_listener, which allows remote authenticated users to cause a denial of service (daemon crash) and possibly execute arbitrary code via a SELECT statement that invokes a pldbg_ function, as demonstrated by (1) pldbg_get_stack and (2) pldbg_abort_target, which triggers use of an uninitialized pointer.
