CVE-2022-3328

CVE-2022-3328 documents a race condition in snap-confine's must_mkdir_and_open_with_perms(), tied to snapd. Connected entries (GHSA-CJQF-877P-7M3F, OSV entries, Debian/Ubuntu advisories) describe a snapd race condition affecting components like snap-confine, with the core issue described as a rac...

CVE-2019-7304

CVE-2019-7304 affects Canonical snapd pre-2.37.1, where socket owner validation on the REST API Unix socket was insufficient, enabling local privilege escalation to root via snapd operations. The vulnerability is documented across multiple feeds (NVD, OSV, CVE listing) with CVSS v3.1 base score 9...

CVE-2023-1523

CVE-2023-1523 affects the snapd sandbox via the TIOCLINUX ioctl. A malicious snap could inject into the terminal input and cause arbitrary commands to execute outside the sandbox after the snap exits, with no impact on graphical terminal emulators (e.g., xterm, GNOME Terminal) and exploitation li...

CVE-2021-44731

CVE-2021-44731 describes a race condition in the snapd ecosystem: the snap-confine binary could be induced to execute arbitrary code when preparing a private mount namespace for a snap, enabling a local attacker to escalate to root. Public details show a local-privilege-escalation path via bind-m...

CVE-2021-44730

CVE-2021-44730 affects snapd: 2.54.2 did not validate the location of the snap-confine binary, enabling a local attacker to hardlink it elsewhere and cause snap-confine to execute arbitrary binaries, achieving privilege escalation. Affected systems may gain root/privilege escalation locally. Reme...

CVE-2019-7303

CVE-2019-7303 affects Canonical snapd before 2.37.4, where the seccomp filter for strict mode snaps could bypass input restrictions by allowing a 64-bit ioctl path (TIOCSTI) to insert characters into a terminal on a 64-bit host. The root cause is a mismatch: seccomp rules target 64-bit ioctl(2) c...

CVE-2021-4120

CVE-2021-4120 affects snapd 2.54.2, where insufficient validation of snap content interface and layout paths allows a snap to inject arbitrary AppArmor policy rules and escape strict snap confinement. The underlying issue is in the content interface and layout declarations, enabling bypass of con...

CVE-2021-3155

CVE-2021-3155 affects snapd up to 2.54.2, where ~/snap directories in users’ home were created with insufficient owner-only permissions, potentially allowing a local attacker to read private data. Fixes are in snapd 2.54.3+18.04, 2.54.3+20.04, and 2.54.3+21.10.1. No exploitation details are provi...

CVE-2020-27352

The CVE-2020-27352 issue affects snapd (e.g., the docker snap and similar snaps) where the systemd service units for these snaps are generated without setting Delegate=yes. This omission allows systemd to move processes from containers managed by the snap into the cgroup of the snap’s main daemon...

CVE-2024-5138

The CVE-2024-5138 issue affects the snapd component snapctl. The root cause is improper parsing/validation of command-line arguments in snapctl, allowing an unprivileged user to trigger an authorised action on behalf of snapd that would normally require administrator privileges. This could lead t...

CVE-2020-11933

The CVE-2020-11933 issue affects Ubuntu Core 16/18 when cloud-init is managed by snapd. It describes cloud-init running with no boot-time restrictions, enabling a physical attacker to craft cloud-init user-data/meta-data on external media to perform arbitrary changes and bypass security controls ...

CVE-2024-1724

CVE-2024-1724 affects snapd prior to 2.62, where AppArmor sandbox enforcement failed to restrict writes to $HOME/bin. In Ubuntu, this path is added to the user PATH when present, enabling a user-wurnished malicious snap using the home plug to drop scripts into PATH and potentially execute them ou...

CVE-2024-29068

In snapd

CVE-2024-29069

In CVE-2024-29069, snapd versions prior to 2.62 fail to validate the destination of symbolic links when extracting a snap from a squashfs image. This can allow a malicious snap to cause snapd to write the linked destination’s contents into a world-readable directory, enabling an unprivileged user...

CVE-2019-11503

CVE-2019-11503 concerns the snap-confine component included in snapd before 2.39, where a symlink race during a chdir() to the caller’s CWD could enable a cwd restore permission bypass. The vulnerability is documented in multiple sources (NVD, OSV) with the same description. The risk context indi...

CVE-2019-11502

CVE-2019-11502 concerns snap-confine in snapd before 2.38, where ownership of a snap application's resources could be set to the UID/GID of the first calling user. This allowed that user to access a private /tmp directory, a local authority issue that attackers could exploit to modify or read tra...
