{"id":"USN-4335-1","summary":"thunderbird vulnerabilities","details":"Multiple security issues were discovered in Thunderbird. If a user were\ntricked in to opening a specially crafted website in a browsing context,\nan attacker could potentially exploit these to cause a denial of service,\nobtain sensitive information, bypass security restrictions, bypass\nsame-origin restrictions, conduct cross-site scripting (XSS) attacks, or\nexecute arbitrary code.

(CVE-2019-11745)\n\nIt was discovered that a specially crafted S/MIME message with an inner\nencryption layer could be displayed as having a valid signature in some\ncircumstances, even if the signer had no access to the encrypted message.\nAn attacker could potentially exploit this to spoof the message author.\n(CVE-2019-11755)\n\nA heap overflow was discovered in the expat library in Thunderbird. If a\nuser were tricked in to opening a specially crafted message, an attacker\ncould potentially exploit this to cause a denial of service, or execute\narbitrary code. (CVE-2019-15903)\n\nIt was discovered that Message ID calculation was based on uninitialized\ndata. An attacker could potentially exploit this to obtain sensitive\ninformation. (CVE-2020-6792)\n\nMutiple security issues were discovered in Thunderbird. If a user were\ntricked in to opening a specially crafted message, an attacker could\npotentially exploit these to cause a denial of service, obtain sensitive\ninformation, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795,\nCVE-2020-6822)\n\nIt was discovered that if a user saved passwords before Thunderbird 60 and\nthen later set a primary password, an unencrypted copy of these passwords\nwould still be accessible. A local user could exploit this to obtain\nsensitive information. (CVE-2020-6794)\n\nIt was discovered that the Devtools’ ‘Copy as cURL’ feature did not\nfully escape website-controlled data. If a user were tricked in to using\nthe ‘Copy as cURL’ feature to copy and paste a command with specially\ncrafted data in to a terminal, an attacker could potentially exploit this\nto execute arbitrary commands via command injection.
