CVE-2020-14040: Fedoraproject Fedora

High severity, CVSS 7.5. EPSS: 1.8% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 32 only
• Golang Text: before 0.3.3 (fixed in 0.3.3)
