Changes in version 0.4.2.8 - 2020-07-09
Tor 0.4.2.8 backports various fixes from later releases, including
several that affect usability and portability.
This release also fixes TROVE-2020-001, a medium-severity denial of
service vulnerability affecting all versions of Tor when compiled with
the NSS encryption library. (This is not the default configuration.)
Using this vulnerability, an attacker could cause an affected Tor
instance to crash remotely. This issue is also tracked as CVE-2020-
15572. Anybody running a version of Tor built with the NSS library
should upgrade to 0.3.5.11, 0.4.2.8, 0.4.3.6, or 0.4.4.2-alpha
or later.
o Major bugfixes (NSS, security, backport from 0.4.4.2-alpha):
- Fix a crash due to an out-of-bound memory access when Tor is
compiled with NSS support. Fixes bug 33119; bugfix on
0.3.5.1-alpha. This issue is also tracked as TROVE-2020-001
and CVE-2020-15572.
