critical Nessus Plugin ID 135896

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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, obtain sensitive information, bypass security restrictions, bypass same-origin restrictions, conduct cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-11757, CVE-2019-11758, CVE-2019-11759, CVE-2019-11760, CVE-2019-11761, CVE-2019-11762, CVE-2019-11763, CVE-2019-11764, CVE-2019-17005, CVE-2019-17008, CVE-2019-17010, CVE-2019-17011, CVE-2019-17012, CVE-2019-17016, CVE-2019-17017, CVE-2019-17022, CVE-2019-17024, CVE-2019-17026, 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 NSS incorrectly handled certain memory operations. A remote attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-11745)

It was discovered that a specially crafted S/MIME message with an inner encryption layer could be displayed as having a valid signature in some circumstances, even if the signer had no access to the encrypted message. An attacker could potentially exploit this to spoof the message author. (CVE-2019-11755)

A heap overflow was discovered in the expat library in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-15903)

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)

It was discovered that the Devtools' 'Copy as cURL' feature did not fully escape website-controlled data. If a user were tricked in to using the 'Copy as cURL' feature to copy and paste a command with specially crafted data in to a terminal, an attacker could potentially exploit this to execute arbitrary commands via command injection.
(CVE-2020-6811).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
