Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-02-05 03:54:38 UTC
Description:
"The function g_bytes_new has an integer overflow due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to a memory corruption vulnerability."

leio's noticed some possible regressions in gnome-shell, gnome-keyring. See https://gitlab.gnome.org/GNOME/glib/-/issues/2305. So let's not rush to jump on 2.66.6 yet.

CVE-2021-27218 was assigned for this (the upstream issue title seems wrong).

Well, maybe not wrong, but both CVEs are similar and appear to be covered by the stabilization in this bug.
