Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: The GNU C Library could be made to crash or run programs. Software Description: - glibc: GNU C Library - eglibc: GNU C Library Details: Siddhesh Poyarekar discovered that the GNU C Library incorrectly handled certain multibyte characters when using the iconv function. An attacker could possibly use this issue to cause applications to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2012-6656) Adhemerval Zanella Netto discovered that the GNU C Library incorrectly handled certain multibyte characters when using the iconv function. An attacker could possibly use this issue to cause applications to crash, resulting in a denial of service. (CVE-2014-6040) Tim Waugh discovered that the GNU C Library incorrectly enforced the WRDE_NOCMD flag when handling the wordexp function. An attacker could possibly use this issue to execute arbitrary commands. (CVE-2014-7817) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: Ubuntu 10.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes.

| Title: | RHSA-2014:2023 -- glibc security and bug fix update (Moderate) | ||
| Description: | The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. It was found that the wordexp() function would perform command substitution even when the WRDE_NOCMD flag was specified. An attacker able to provide specially crafted input to an application using the wordexp() function, and not sanitizing the input correctly, could potentially use this flaw to execute arbitrary commands with the credentials of the user running that application. (CVE-2014-7817) This issue was discovered by Tim Waugh of the Red Hat Developer Experience Team. This update also fixes the following bug: * Prior to this update, if a file stream that was opened in append mode and its underlying file descriptor were used at the same time and the file was truncated using the ftruncate() function on the file descriptor, a subsequent ftell() call on the stream incorrectly modified the file offset by seeking to the new end of the file. This update ensures that ftell() modifies the state of the file stream only when it is in append mode and its buffer is not empty. As a result, the described incorrect changes to the file offset no longer occur. (BZ#1170187) All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. | ||
