Revision History: August 6 2019: Added DLA 1866-2 fixing a regression in Debian 8 Jessie. August 1 2019: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Package : glib2.0 Version : 2.42.1-1+deb8u2 CVE ID : CVE-2018-16428 CVE-2018-16429 CVE-2019-13012 Debian Bug : 931234 Various minor issues have been addressed in the GLib library. GLib is a useful general-purpose C library used by projects such as GTK+, GIMP, and GNOME. CVE-2018-16428 In GNOME GLib, g_markup_parse_context_end_parse() in gmarkup.c had a NULL pointer dereference. CVE-2018-16429 GNOME GLib had an out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c, related to utf8_str(). CVE-2019-13012 The keyfile settings backend in GNOME GLib (aka glib2.0) before created directories using g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL). Consequently, it did not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions were used; for files, default file permissions were used. This issue is similar to CVE-2019-12450. For Debian 8 "Jessie", these problems have been fixed in version 2.42.1-1+deb8u2. We recommend that you upgrade your glib2.0 packages.
