Vulnerability from fkie_nvd - Published: 2014-05-23 14:55 - Updated: 2026-06-16 23:52
Severity
Summary
The Portable Tool Library (aka PTLib) before 2.10.10, as used in Ekiga before 4.0.1, does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted PXML document containing a large number of nested entity references, aka a "billion laughs attack."
