CVE-2008-3933
Wireshark (formerly Ethereal) 0.10.14 through 1.0.2 allows attackers to cause a denial of service (crash) via a packet with crafted zlib-compressed data that triggers an invalid read in the tvb_uncompress function.
Does this matter?
Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.
