CVE-2013-1864
Last modified
CVE-2013-1864 is a vulnerability of currently unknown severity. 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.". EPSS estimates a 2.85% chance of exploitation in the next 30 days.
