Name of the Vulnerable Software and Affected Versions: x/text versions 1.15.4

Description: An "index out of range" panic occurs in language.ParseAcceptLanguage while parsing the -u- extension. The x/text/language package is supposed to be able to parse an HTTP Accept-Language header.

Recommendations: For version 1.15.4, consider updating to a newer version to mitigate the risk, however, at the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting the parsing of HTTP Accept-Language headers to minimize the risk of exploitation.
