CVE-2011-2175 is a vulnerability of currently unknown severity. Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.. EPSS estimates a 2.10% chance of exploitation in the next 30 days.
