Partial Red Hat: 28 fixed, 27 without a fix

Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and Red Hat. Impact type from CWE-770.

Summary

The Go standard library packages net/textproto and mime/multipart are affected from 0 before 1.26.9 and from 1.27.0-0 before 1.27.2. Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when fewer than 400 bytes remain in the limit at the start of a part (CWE-770). A remote attacker without privileges or user interaction can exhaust memory, affecting availability.

Description from the CNA
