MEDIUM 5.5EPSS 1.40%

Does this matter?

Lower severity and a low EPSS score (1.40%). Track it; it rarely justifies an emergency change on its own.

Description

In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the RTSE dissector and other ASN.1 dissectors could crash. This was addressed in epan/charsets.c by adding a get_t61_string length check.
