Scientific Linux Security Update : ccid on SL5.x i386/x86_64
Medium Nessus Plugin ID 70388
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionAn integer overflow, leading to an array index error, was found in the way the CCID driver processed a smart card's serial number. A local attacker could use this flaw to execute arbitrary code with the privileges of the user running the PC/SC Lite pcscd daemon (root, by default), by inserting a specially crafted smart card. (CVE-2010-4530)
This update also fixes the following bug :
- The pcscd service failed to read from the SafeNet Smart Card 650 v1 when it was inserted into a smart card reader. The operation failed with a 'IFDHPowerICC() PowerUp failed' error message. This was due to the card taking a long time to respond with a full Answer To Reset (ATR) request, which lead to a timeout, causing the card to fail to power up. This update increases the timeout value so that the aforementioned request is processed properly, and the card is powered on as expected.
SolutionUpdate the affected ccid and / or ccid-debuginfo packages.
