25 May 2018
thunderbird vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 18.04 LTS
o Ubuntu 17.10
o Ubuntu 16.04 LTS
o Ubuntu 14.04 LTS
Summary
Several security issues were fixed in Thunderbird.
Software Description
o thunderbird - Mozilla Open Source mail and newsgroup client
Details
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 via application
crash, install lightweight themes without user interaction, or execute
arbitrary code. (CVE-2018-5150, CVE-2018-5154, CVE-2018-5155, CVE-2018-5159,
CVE-2018-5168, CVE-2018-5178)
An issue was discovered when processing message headers 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 via application hang.
(CVE-2018-5161)
It was discovered encrypted messages could leak plaintext via the src attribute
of remote images or links. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2018-5162)
It was discovered that the filename of an attachment could be spoofed. An
attacker could potentially exploit this by tricking the user in to opening an
attachment of a different type to the one expected. (CVE-2018-5170)
Multiple security issues were discovered in Skia. If a user were tricked in to
opening a specially crafted message, an attacker could potentially exploit
these to cause a denial of service via application crash, or execute arbitrary
code. (CVE-2018-5183)
It was discovered that S/MIME encrypted messages with remote content could leak
plaintext via a chosen-ciphertext attack. An attacker could potentially exploit
this to obtain sensitive information. (CVE-2018-5184)
It was discovered that plaintext of decrypted emails could leak by submitting
an embedded form. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2018-5185)
