DLA-1825-1 kdepim -- LTS security update

Date Reported:

18 Jun 2019

Affected Packages:

kdepim

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 926996.
In Mitre's CVE dictionary: CVE-2019-10732.

More information:

A reply-based decryption oracle was found in kdepim, which provides the KMail e-mail client.

An attacker in possession of S/MIME or PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, they unknowingly leak the plaintext of the encrypted message part(s) back to the attacker.

For Debian 8 Jessie, this problem has been fixed in version 4:4.14.1-1+deb8u2.

We recommend that you upgrade your kdepim packages.
