Name of the Vulnerable Software and Affected Versions: x/text versions prior to 0.3.5 x/text version 1.15.4

Description: A "slice bounds out of range" panic occurs in language.ParseAcceptLanguage while processing a BCP 47 tag. The x/text/language package is supposed to be able to parse an HTTP Accept-Language header.

Recommendations: For versions prior to 0.3.5, update to version 0.3.5 or later. For version 1.15.4, update to a version later than 1.15.4. As a temporary workaround, consider disabling the language.ParseAcceptLanguage function until a patch is available.
