Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : Go Text vulnerabilities (USN-5873-1)

high Nessus Plugin ID 171575

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5873-1 advisory.

 - The x/text package before 0.3.3 for Go has a vulnerability in encoding/unicode that could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory. An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String. (CVE-2020-14040)

 - In x/text in Go 1.15.4, an index out of range panic occurs in language.ParseAcceptLanguage while parsing the -u- extension. (x/text/language is supposed to be able to parse an HTTP Accept-Language header.) (CVE-2020-28851)

 - In x/text in Go before v0.3.5, a slice bounds out of range panic occurs in language.ParseAcceptLanguage while processing a BCP 47 tag. (x/text/language is supposed to be able to parse an HTTP Accept-Language header.) (CVE-2020-28852)

 - golang.org/x/text/language in golang.org/x/text before 0.3.7 can panic with an out-of-bounds read during BCP 47 language tag parsing. Index calculation is mishandled. If parsing untrusted user input, this can be used as a vector for a denial-of-service attack. (CVE-2021-38561)

 - An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse. (CVE-2022-32149)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected golang-golang-x-text-dev and / or golang-x-text-dev packages.
