Affected Functions

Version

gettext_rs::TextDomain::init

• <0.8.0

gettext_rs::setlocale

• <0.8.0

Description

setlocale and TextDomain::init are unsound and may allow safe code to exhibit undefined behavior when called in a multi-threaded program.

The flaw is fixed in 0.8.0 by marking these functions unsafe and documenting the conditions under which they can be called safely.
