Calendar Grey March 14, 2021
Dist Opensuse Esm H88
A critical patch for libpng has been released to fix buffer overflow vulnerabilities in Fedora 34.
An update that fixes two vulnerabilities is now available

Description

This update for glib2 fixes the following issues:

- CVE-2021-27218: g_byte_array_new_take takes a gsize as length but stores

in a guint, this patch will refuse if the length is larger than guint.

(bsc#1182328)

- CVE-2021-27219: g_memdup takes a guint as parameter and sometimes leads

into an integer overflow, so add a g_memdup2 function which uses gsize

to replace it. (bsc#1182362)

This update was imported from the SUSE:SLE-15-SP2:Update update project.
