A heap-based buffer overflow flaw was found in cpio’s list_file() function. An attacker could provide a specially crafted archive that, when processed by cpio, would crash cpio, or potentially lead to arbitrary code execution. (CVE-2014-9112)

This update fixes the following bugs :

  • Previously, during archive creation, cpio internals did not detect a read() system call failure. Based on the premise that the call succeeded, cpio terminated unexpectedly with a segmentation fault without processing further files. The underlying source code has been patched, and an archive is now created successfully.

  • Previously, running the cpio command without parameters on Scientific Linux 7 with Russian as the default language resulted in an error message that was not accurate in Russian due to an error in spelling. This has been corrected and the Russian error message is spelled correctly.
