AlmaLinux 8 : GNOME (ALSA-2020:1766)

high Nessus Plugin ID 157605

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2020:1766 advisory.

 - There is a stack-based buffer overflow in the parse_makernote function of dcraw_common.cpp in LibRaw 0.19.1. Crafted input will lead to a denial of service or possibly unspecified other impact.
 (CVE-2018-20337)

 - A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session. (CVE-2019-3825)

 - An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used. (CVE-2019-12447)

 - An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c has race conditions because the admin backend doesn't implement query_info_on_read/write. (CVE-2019-12448)

 - An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a file's user and group ownership during move (and copy with G_FILE_COPY_ALL_METADATA) operations from admin:// to file:// URIs, because root privileges are unavailable. (CVE-2019-12449)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
