VUL-0: CVE-2021-29949: MozillaThunderbird: might execute an alternative OTR library
Last modified: 2021-04-21 11:44:40 UTC
rh#1951872 When loading the shared library that provides the OTR protocol implementation, Thunderbird will initially attempt to open it using a filename that isn't distributed by Thunderbird. If a computer has already been infected with a malicious library of the alternative filename, and the malicious library has been copied to a directory that is contained in the search path for executable libraries, then Thunderbird will load the incorrect library.
