Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS / 16.10 : pcsc-lite vulnerability (USN-3176-1)

Medium Nessus Plugin ID 96719


The remote Ubuntu host is missing a security-related patch.


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.

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.


Update the affected pcscd package.
