GLSA-201702-01 : PCSC-Lite: Multiple vulnerabilities

high Nessus Plugin ID 96916

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201702-01 (PCSC-Lite: Multiple vulnerabilities)

The SCardReleaseContext function normally releases resources associated with the given handle (including “cardsList”) and clients should cease using this handle. However, a malicious client can make the daemon invoke SCardReleaseContext and continue issuing other commands that use “cardsList”, resulting in a use-after-free. When SCardReleaseContext is invoked multiple times it additionally results in a double-free of “cardsList”.
Impact :

A local attacker could use a malicious client to connect to pcscd’s Unix socket, possibly resulting in a Denial of Service condition or privilege escalation since the daemon is running as root.
Workaround :

There is no known workaround at this time.

Solution

All PCSC-Lite users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/pcsc-lite-1.8.20'
