USN-5292-1 fixed vulnerabilities in snapd. This update provides the
corresponding update for the riscv64 architecture.
Original advisory details:
James Troup discovered that snap did not properly manage the permissions for
the snap directories. A local attacker could possibly use this issue to expose
sensitive information. (CVE-2021-3155)
Ian Johnson discovered that snapd did not properly validate content interfaces
and layout paths. A local attacker could possibly use this issue to inject
arbitrary AppArmor policy rules, resulting in a bypass of intended access
restrictions. (CVE-2021-4120)
The Qualys Research Team discovered that snapd did not properly validate the
location of the snap-confine binary. A local attacker could possibly use this
issue to execute other arbitrary binaries and escalate privileges.
(CVE-2021-44730)
The Qualys Research Team discovered that a race condition existed in the snapd
snap-confine binary when preparing a private mount namespace for a snap. A
local attacker could possibly use this issue to escalate privileges and
execute arbitrary code. (CVE-2021-44731)
It was discovered that the Packet network protocol implementation in the
Linux kernel contained a double-free vulnerability. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2021-22600)
Jann Horn discovered a race condition in the Unix domain socket
implementation in the Linux kernel that could result in a read-after-free.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2021-4083)
Kirill Tkhai discovered that the XFS file system implementation in the
Linux kernel did not calculate size correctly when pre-allocating space in
some situations. A local attacker could use this to expose sensitive
information. (CVE-2021-4155)
Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in
the Linux kernel did not perform a GPU TLB flush in some situations. A
local attacker could use this to cause a denial of service or possibly
execute arbitrary code. (CVE-2022-0330)
It was discovered that the VMware Virtual GPU driver in the Linux kernel
did not properly handle certain failure conditions, leading to a stale
entry in the file descriptor table. A local attacker could use this to
expose sensitive information or possibly gain administrative privileges.
(CVE-2022-22942)
Two security issues were found in PHP, a widely-used open source general
purpose scripting language which could result in information disclosure
or denial of service.
Multiple vulnerabilties were discovered in snapd, a daemon and tooling
that enable Snap packages, which could result in bypass of access
restrictions or privilege escalation.
A reflected cross-site scripting (XSS) vulnerability in PHP-Fusion 7.02.07 allows remote attackers to inject arbitrary web script or HTML via the status parameter in the CMS admin panel.
