Software Description o thunderbird - Mozilla Open Source mail and newsgroup client Details It was discovered that Message ID calculation was based on uninitialized data. An attacker could potentially exploit this to obtain sensitive information. (CVE-2020-6792) Mutiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795, CVE-2020-6822) It was discovered that if a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords would still be accessible. A local user could exploit this to obtain sensitive information. (CVE-2020-6794) Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, conduct cross-site scripting (XSS) attacks, obtain sensitive information, or execute arbitrary code. (CVE-2019-20503, CVE-2020-6798, CVE-2020-6800, CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814, CVE-2020-6819, CVE-2020-6820, CVE-2020-6821, CVE-2020-6825) It was discovered that the Devtools Copy as cURL feature did not fully escape website-controlled data.
