CVE-2021-3470 (GCVE-0-2021-3470)

Vulnerability from cvelistv5 – Published: 2021-03-31 13:44 – Updated: 2024-08-03 16:53

Summary

A heap overflow issue was found in Redis in versions before 5.0.10, before 6.0.9 and before 6.2.0 when using a heap allocator other than jemalloc or glibc's malloc, leading to potential out of bound write or process crash. Effectively this flaw does not affect the vast majority of users, who use jemalloc or glibc malloc.

Severity

No CVSS data available.
