Synopsis: Moderate: pcsc-lite security and bug fix update Issue Date: 2013-02-21 CVE Numbers: CVE-2010-4531 -- A stack-based buffer overflow flaw was found in the way pcsc-lite decoded certain attribute values of Answer-to-Reset (ATR) messages. A local attacker could use this flaw to execute arbitrary code with the privileges of the user running the pcscd daemon (root, by default), by inserting a specially-crafted smart card. (CVE-2010-4531) This update also fixes the following bugs: * Due to an error in the init script, the chkconfig utility did not automatically place the pcscd init script after the start of the HAL daemon. Consequently, the pcscd service did not start automatically at boot time. With this update, the pcscd init script has been changed to explicitly start only after HAL is up, thus fixing this bug. * Because the chkconfig settings and the startup files in the /etc/rc.d/ directory were not changed during the update described in the SLBA-2012:0990 advisory, the user had to update the chkconfig settings manually to fix the problem. Now, the chkconfig settings and the startup files in the /etc/rc.d/ directory are automatically updated as expected. * Previously, the SCardGetAttrib() function did not work properly and always returned the "SCARD_E_INSUFFICIENT_BUFFER" error regardless of the actual buffer size. This update applies a patch to fix this bug and the SCardGetAttrib() function now works as expected. After installing this update, the pcscd daemon will be restarted automatically. -- SL6 x86_64 pcsc-lite-1.5.2-11.el6.x86_64.rpm pcsc-lite-debuginfo-1.5.2-11.el6.i686.rpm pcsc-lite-debuginfo-1.5.2-11.el6.x86_64.rpm pcsc-lite-libs-1.5.2-11.el6.i686.rpm pcsc-lite-libs-1.5.2-11.el6.x86_64.rpm pcsc-lite-devel-1.5.2-11.el6.i686.rpm pcsc-lite-devel-1.5.2-11.el6.x86_64.rpm pcsc-lite-doc-1.5.2-11.el6.x86_64.rpm i386 pcsc-lite-1.5.2-11.el6.i686.rpm pcsc-lite-debuginfo-1.5.2-11.el6.i686.rpm pcsc-lite-libs-1.5.2-11.el6.i686.rpm pcsc-lite-devel-1.5.2-11.el6.i686.rpm pcsc-lite-doc-1.5.2-11.el6.i686.rpm - Scientific Linux Development Team
