Alibaba Cloud Linux 3 : 0108: GNOME (ALINUX3-SA-2022:0108)

high Nessus Plugin ID 236504

Synopsis

The remote Alibaba Cloud Linux host is missing one or more security updates.

Description

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0108 advisory.

 Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

 CVE-2018-20337:
 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-2019-3825:
 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-2019-3827:
 An incorrect permission check in the admin backend in gvfs before version 1.39.4 was found that allows reading and modify arbitrary files by privileged users without asking for password when no authentication agent is running. This vulnerability can be exploited by malicious programs running under privileges of users belonging to the wheel group to further escalate its privileges by modifying system files without user's knowledge. Successful exploitation requires uncommon system configuration.

 CVE-2019-12447:
 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-2019-12448:
 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-2019-12449:
 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-2019-12795:
 daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3 opened a private D-Bus server socket without configuring an authorization rule. A local attacker could connect to this server socket and issue D-Bus method calls.(Note that the server socket only accepts a single connection, so the attacker would have to discover the server and connect to the socket before its owner does.)

 CVE-2019-15690:
 ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.

 CVE-2019-20839:
 libvncclient/sockets.c in LibVNCServer before 0.9.13 has a buffer overflow via a long socket filename.

 CVE-2020-14397:
 An issue was discovered in LibVNCServer before 0.9.13. libvncserver/rfbregion.c has a NULL pointer dereference.

 CVE-2020-14405:
 An issue was discovered in LibVNCServer before 0.9.13. libvncclient/rfbproto.c does not limit TextChat size.

 CVE-2020-15503:
 LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.

 CVE-2020-25708:
 A divide by zero issue was found to occur in libvncserver-0.9.12. A malicious client could use this flaw to send a specially crafted message that, when processed by the VNC server, would lead to a floating point exception, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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

Solution

Update the affected packages.
