UnknownEPSS 1.82%

Last modified

CVE-2014-3227 is a vulnerability of currently unknown severity. dpkg 1.15.9, 1.16.x before 1.16.14, and 1.17.x before 1.17.9 expect the patch program to be compliant with a need for the "C-style encoded filenames" feature, but is supported in environments with noncompliant patch programs, which triggers an interaction error that allows remote attackers to conduct directory traversal attacks and modify files outside of the intended directories via a crafted source package. NOTE: this vulnerability exists because of reliance on unrealistic constraints on the behavior of an external program.. EPSS estimates a 1.82% chance of exploitation in the next 30 days.
