"details": "USN-5292-1 fixed a vulnerability in snapd. Unfortunately that update introduced\na regression that could break the fish shell. This update fixes the problem.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n James Troup discovered that snap did not properly manage the permissions for\n the snap directories. A local attacker could possibly use this issue to expose\n sensitive information. (CVE-2021-3155)\n \n Ian Johnson discovered that snapd did not properly validate content interfaces\n and layout paths. A local attacker could possibly use this issue to inject\n arbitrary AppArmor policy rules, resulting in a bypass of intended access\n restrictions. (CVE-2021-4120)\n \n The Qualys Research Team discovered that snapd did not properly validate the\n location of the snap-confine binary. A local attacker could possibly use this\n issue to execute other arbitrary binaries and escalate privileges.\n (CVE-2021-44730)\n \n The Qualys Research Team discovered that a race condition existed in the snapd\n snap-confine binary when preparing a private mount namespace for a snap. A\n local attacker could possibly use this issue to escalate privileges and\n execute arbitrary code. (CVE-2021-44731)\n",
