CVE-2024-24784: Go Standard Library Net/mail

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

The ParseAddressList function incorrectly handles comments (text within parentheses) within display names. Since this is a misalignment with conforming address parsers, it can result in different trust decisions being made by programs using different parsers.

Affected products

• Go Standard Library Net/mail: before 1.21.8 (fixed in 1.21.8); from 1.22.0-0, before 1.22.1 (fixed in 1.22.1)
• Go Standard Library Net\/mail: before 1.21.8 (fixed in 1.21.8); from 1.22.0-0, before 1.22.1 (fixed in 1.22.1)
