Use-after-free vulnerability in pcsc-lite before 1.8.20 allows a remote attackers to cause denial of service (crash) via a command that uses "cardsList" after the handle has been released through the SCardReleaseContext function.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - pcsc-lite: Use-after-free of cardsList due to SCardReleaseContext invocations (CVE-2016-10109)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

According to the version of the pcsc-lite packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

According to the version of the pcsc-lite packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - The purpose of PC/SC Lite is to provide a Windows(R)     SCard interface in a very small form factor for     communicating to smartcards and readers. PC/SC Lite     uses the same winscard API as used under Windows(R).
    This package includes the PC/SC Lite daemon, a resource     manager that coordinates communications with smart card     readers and smart cards that are connected to the     system, as well as other command line tools.Security     Fix(es):Use-after-free vulnerability in pcsc-lite     before 1.8.20 allows a remote attackers to cause denial     of service (crash) via a command that uses 'cardsList'     after the handle has been released through the     SCardReleaseContext function.(CVE-2016-10109)

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 &ldquo;cardsList&rdquo;) and clients should       cease using this handle. However, a malicious client can make the daemon       invoke SCardReleaseContext and continue issuing other commands that use       &ldquo;cardsList&rdquo;, resulting in a use-after-free. When SCardReleaseContext       is invoked multiple times it additionally results in a double-free of       &ldquo;cardsList&rdquo;.
  Impact :

    A local attacker could use a malicious client to connect to pcscd&rsquo;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.

pcsc-lite was updated to fix one security issue. This security issue was fixed :

  - CVE-2016-10109: This use-after-free and double-free     issue allowed local attacker to cause a Denial of     Service and possible privilege escalation (bsc#1017902).

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

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3176-1 advisory.

    Peter Wu discovered that the PC/SC service did not correctly handle certain resources. A local attacker     could use this issue to cause PC/SC to crash, resulting in a denial of service, or possibly execute     arbitrary code with root privileges.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Peter Wu on Openwall mailing-list reports :

The issue allows a local attacker to cause a Denial of Service, but can potentially result in Privilege Escalation since the daemon is running as root. while any local user can connect to the Unix socket.
Fixed by patch which is released with hpcsc-lite 1.8.20.

It was discovered that there was a use-after-free and double-free vulnerability in pcsc-lite, a library to access smart cards that use the Windows(R) SCard interface ('PC/SC').

For Debian 7 'Wheezy', this issue has been fixed in pcsc-lite version 1.8.4-1+deb7u2.

We recommend that you upgrade your pcsc-lite packages.

Peter Wu discovered that a use-after-free in the pscd PC/SC daemon of PCSC-Lite might result in denial of service or potentially privilege escalation.
