{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/36039?format=json","vulnerability_id":"VCID-qyby-143d-b7gz","summary":"B2 Command Line Tool is the official command line tool for the backblaze cloud storage service. Linux and Mac releases of the B2 command-line tool version 3.2.0 and below contain a key disclosure vulnerability that, in certain conditions, can be exploited by local attackers through a time-of-check-time-of-use (TOCTOU) race condition. The command line tool saves API keys (and bucket name-to-id mapping) in a local database file (`$XDG_CONFIG_HOME/b2/account_info`, `~/.b2_account_info` or a user-defined path) when `b2 authorize-account` is first run. This happens regardless of whether a valid key is provided or not. When first created, the file is world readable and is (typically a few milliseconds) later altered to be private to the user. If the directory is readable by a local attacker and the user did not yet run `b2 authorize-account` then during the brief period between file creation and permission modification, a local attacker can race to open the file and maintain a handle to it. This allows the local attacker to read the contents after the file after the sensitive information has been saved to it. Users that have not yet run `b2 authorize-account` should upgrade to B2 Command-Line Tool v3.2.1 before running it. Users that have run `b2 authorize-account` are safe if at the time of the file creation no other local users had read access to the local configuration file. Users that have run `b2 authorize-account` where the designated path could be opened by another local user should upgrade to B2 Command-Line Tool v3.2.1 and remove the database and regenerate all application keys. Note that `b2 clear-account` does not remove the database file and it should not be used to ensure that all open handles to the file are invalidated. If B2 Command-Line Tool cannot be upgraded to v3.2.1 due to a dependency conflict, a binary release can be used instead. Alternatively a new version could be installed within a virtualenv, or the permissions can be changed to prevent local users from opening the database file.","aliases":[{"alias":"CVE-2022-23653"},{"alias":"GHSA-8wr4-2wm6-w3pr"},{"alias":"PYSEC-2022-32"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/26740?format=json","purl":"pkg:pypi/b2@3.2.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@3.2.1"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/26697?format=json","purl":"pkg:pypi/b2@0.3.14","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.3.14"},{"url":"http://public2.vulnerablecode.io/api/packages/26698?format=json","purl":"pkg:pypi/b2@0.4.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.0"},{"url":"http://public2.vulnerablecode.io/api/packages/26699?format=json","purl":"pkg:pypi/b2@0.4.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.2"},{"url":"http://public2.vulnerablecode.io/api/packages/26700?format=json","purl":"pkg:pypi/b2@0.4.4","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.4"},{"url":"http://public2.vulnerablecode.io/api/packages/26701?format=json","purl":"pkg:pypi/b2@0.4.6","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.6"},{"url":"http://public2.vulnerablecode.io/api/packages/26702?format=json","purl":"pkg:pypi/b2@0.4.8","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.8"},{"url":"http://public2.vulnerablecode.io/api/packages/26703?format=json","purl":"pkg:pypi/b2@0.4.10","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.10"},{"url":"http://public2.vulnerablecode.io/api/packages/26704?format=json","purl":"pkg:pypi/b2@0.5.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.5.0"},{"url":"http://public2.vulnerablecode.io/api/packages/26705?format=json","purl":"pkg:pypi/b2@0.5.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.5.2"},{"url":"http://public2.vulnerablecode.io/api/packages/26706?format=json","purl":"pkg:pypi/b2@0.5.4","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.5.4"},{"url":"http://public2.vulnerablecode.io/api/packages/26707?format=json","purl":"pkg:pypi/b2@0.5.6","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.5.6"},{"url":"http://public2.vulnerablecode.io/api/packages/26708?format=json","purl":"pkg:pypi/b2@0.6.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.6.0"},{"url":"http://public2.vulnerablecode.io/api/packages/26709?format=json","purl":"pkg:pypi/b2@0.6.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.6.2"},{"url":"http://public2.vulnerablecode.io/api/packages/26710?format=json","purl":"pkg:pypi/b2@0.6.4","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.6.4"},{"url":"http://public2.vulnerablecode.io/api/packages/26711?format=json","purl":"pkg:pypi/b2@0.6.6","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.6.6"},{"url":"http://public2.vulnerablecode.io/api/packages/26712?format=json","purl":"pkg:pypi/b2@0.6.8","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.6.8"},{"url":"http://public2.vulnerablecode.io/api/packages/26713?format=json","purl":"pkg:pypi/b2@0.7.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-qyby-143d-b7gz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.7.0"},{"url":"http
