CVE-2016-2522

UnknownEPSS 2.08%

Last modified

CVE-2016-2522 is a vulnerability of currently unknown severity. The dissect_ber_constrained_bitstring function in epan/dissectors/packet-ber.c in the ASN.1 BER dissector in Wireshark 2.0.x before 2.0.2 does not verify that a certain length is nonzero, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet.. EPSS estimates a 2.08% chance of exploitation in the next 30 days.
