UBUNTU-CVE-2024-1724 (CVE-2024-1724)

Vulnerability from osv_ubuntu – Published: 2024-07-01 00:00 – Updated: 2025-10-10 15:16 – Source website

Details

In snapd versions prior to 2.62, when using AppArmor for enforcement of sandbox permissions, snapd failed to restrict writes to the $HOME/bin path. In Ubuntu, when this path exists, it is automatically added to the users PATH. An attacker who could convince a user to install a malicious snap which used the 'home' plug could use this vulnerability to install arbitrary scripts into the users PATH which may then be run by the user outside of the expected snap sandbox and hence allow them to escape confinement.

USN-6940-1 (UBUNTU-CVE-2024-1724)

Vulnerability from osv_ubuntu – Published: 2024-08-01 06:35 – Updated: 2026-02-10 04:44 – Source website

Summary

snapd vulnerabilities

Details

Neil McPhail discovered that snapd did not properly restrict writes to the $HOME/bin path in the AppArmor profile for snaps using the home plug. An attacker who could convince a user to install a malicious snap could use this vulnerability to escape the snap sandbox. (CVE-2024-1724)

Zeyad Gouda discovered that snapd failed to properly check the file type when extracting a snap. An attacker who could convince a user to install a malicious snap containing non-regular files could then cause snapd to block indefinitely while trying to read from such files and cause a denial of service. (CVE-2024-29068)

Zeyad Gouda discovered that snapd failed to properly check the destination of symbolic links when extracting a snap. An attacker who could convince a user to install a malicious snap containing crafted symbolic links could then cause snapd to write out the contents of the symbolic link destination into a world-readable directory. This in-turn could allow a local unprivileged user to gain access to privileged information. (CVE-2024-29069)

  "details": "USN-6940-1 fixed vulnerabilities in snapd. This update provides the \ncorresponding updates for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS.\n\nOriginal advisory details:\n\n Neil McPhail discovered that snapd did not properly restrict writes to\n the /home/jslarraz/bin path in the AppArmor profile for snaps using the home\n plug. An attacker who could convince a user to install a malicious snap\n could use this vulnerability to escape the snap sandbox. (CVE-2024-1724)\n \n Zeyad Gouda discovered that snapd failed to properly check the file type\n when extracting a snap. An attacker who could convince a user to install\n a malicious snap containing non-regular files could then cause snapd to\n block indefinitely while trying to read from such files and cause a\n denial of service. (CVE-2024-29068)\n \n Zeyad Gouda discovered that snapd failed to properly check the\n destination of symbolic links when extracting a snap. An attacker who\n could convince a user to install a malicious snap containing crafted\n symbolic links could then cause snapd to write out the contents of the\n symbolic link destination into a world-readable directory. This in-turn\n could allow a local unprivileged user to gain access to privileged\n information. (CVE-2024-29069)\n",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
