CVE-2015-1781

TITLE

GNU C Library of gethostbyname_r And other unspecified NSS Buffer overflow vulnerability in functions

DESCRIPTION

Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer. GNU glibc is prone to multiple buffer-overflow vulnerabilities because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. An attacker can exploit these issues to execute arbitrary code in the context of the affected application. Failed exploit attempts may crash the application, denying service to legitimate users. The updated packages provides a solution for these security issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-7423 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1781 https://rhn.redhat.com/errata/RHSA-2015-0863.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 92aa475c44c712eaf19898ef76e04183 mbs1/x86_64/glibc-2.14.1-12.12.mbs1.x86_64.rpm 606cdd33e041f9853eae18f53c9d73de mbs1/x86_64/glibc-devel-2.14.1-12.12.mbs1.x86_64.rpm 133deb850840d464335e5c659cba1627 mbs1/x86_64/glibc-doc-2.14.1-12.12.mbs1.noarch.rpm 7a3d5170647c52cd4a34d2dcda711397 mbs1/x86_64/glibc-doc-pdf-2.14.1-12.12.mbs1.noarch.rpm 96c842afb6110ac18a40b843b51548fc mbs1/x86_64/glibc-i18ndata-2.14.1-12.12.mbs1.x86_64.rpm 703e73278d416a53096fe19c7652c95e mbs1/x86_64/glibc-profile-2.14.1-12.12.mbs1.x86_64.rpm 12f09ed16d9c4b0f9a94e931569dacc3 mbs1/x86_64/glibc-static-devel-2.14.1-12.12.mbs1.x86_64.rpm 09715361d0af4a4dd5fba44239c5e690 mbs1/x86_64/glibc-utils-2.14.1-12.12.mbs1.x86_64.rpm c9a293ac29070d215eb1988bba58aaec mbs1/x86_64/nscd-2.14.1-12.12.mbs1.x86_64.rpm 8d8b74de2d7c0e982e0ad82ac73091b2 mbs1/SRPMS/glibc-2.14.1-12.12.mbs1.src.rpm Mandriva Business Server 2/X86_64: e59cee8712d211add638c1b6c1952fa6 mbs2/x86_64/glibc-2.18-10.2.mbs2.x86_64.rpm baf9e44f8c4f82c75a0154d44b6fce72 mbs2/x86_64/glibc-devel-2.18-10.2.mbs2.x86_64.rpm f3eb6e3ed435f8a06dcffbfa7a44525b mbs2/x86_64/glibc-doc-2.18-10.2.mbs2.noarch.rpm 5df45f7cae82ef7d354fa14c7ac363c9 mbs2/x86_64/glibc-i18ndata-2.18-10.2.mbs2.x86_64.rpm 24ef48d58c7a4114068e7b70dbefad79 mbs2/x86_64/glibc-profile-2.18-10.2.mbs2.x86_64.rpm 5f67c12f02dbc3f4cbf78f1a8c7d5ad5 mbs2/x86_64/glibc-static-devel-2.18-10.2.mbs2.x86_64.rpm f24e67e1ed1b01e5305c28b3a9b02852 mbs2/x86_64/glibc-utils-2.18-10.2.mbs2.x86_64.rpm bae4b399bc43be8af24ddd93257ca31a mbs2/x86_64/nscd-2.18-10.2.mbs2.x86_64.rpm 740d9b3d14292be8847da92243340b62 mbs2/SRPMS/glibc-2.18-10.2.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.

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 discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data. (CVE-2013-7423) A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. (CVE-2015-1781) A heap-based buffer overflow flaw and a stack overflow flaw were found in glibc's swscanf() function. (CVE-2015-1472, CVE-2015-1473) An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. (BZ#1195762) A flaw was found in the way glibc's fnmatch() function processed certain malformed patterns. An attacker able to make an application call this function could use this flaw to crash that application. (BZ#1197730) The CVE-2015-1781 issue was discovered by Arjun Shankar of Red Hat. These updated glibc packages also include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. For information on the most significant of these changes, users are directed to the following article on the Red Hat Customer Portal: https://access.redhat.com/articles/2050743 All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. 4.

Software Description: - glibc: GNU C Library - eglibc: GNU C Library Details: USN-2985-1 fixed vulnerabilities in the GNU C Library. The fix for CVE-2014-9761 introduced a regression which affected applications that use the libm library but were not fully restarted after the upgrade. This update removes the fix for CVE-2014-9761 and a future update will be provided to address this issue. We apologize for the inconvenience.

(CVE-2015-5277) Adam Nielsen discovered that the strftime function in the GNU C Library did not properly handle out-of-range argument data. (CVE-2015-8776) Hector Marco and Ismael Ripoll discovered that the GNU C Library allowed the pointer-guarding protection mechanism to be disabled by honoring the LD_POINTER_GUARD environment variable across privilege boundaries. (CVE-2015-8777) Szabolcs Nagy discovered that the hcreate functions in the GNU C Library did not properly check its size argument, leading to an integer overflow. (CVE-2015-8778) Maksymilian Arciemowicz discovered a stack-based buffer overflow in the catopen function in the GNU C Library when handling long catalog names. (CVE-2015-8779) Florian Weimer discovered that the getnetbyname implementation in the GNU C Library did not properly handle long names passed as arguments. (CVE-2016-3075) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: libc-bin 2.21-0ubuntu4.3 libc6 2.21-0ubuntu4.3 libc6-dev 2.21-0ubuntu4.3 Ubuntu 14.04 LTS: libc-bin 2.19-0ubuntu6.9 libc6 2.19-0ubuntu6.9 libc6-dev 2.19-0ubuntu6.9 Ubuntu 12.04 LTS: libc-bin 2.15-0ubuntu10.15 libc6 2.15-0ubuntu10.15 libc6-dev 2.15-0ubuntu10.15 After a standard system update you need to reboot your computer to make all the necessary changes. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201602-02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: GNU C Library: Multiple vulnerabilities Date: February 17, 2016 Bugs: #516884, #517082, #521932, #529982, #532874, #538090, #538814, #540070, #541246, #541542, #547296, #552692, #574880 ID: 201602-02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in the GNU C library, the worst allowing for remote execution of arbitrary code. * The strftime() function access invalid memory when passed out-of-range data, resulting in a crash (CVE-2015-8776). * Multiple unbounded stack allocations were found in the catopen() function (CVE-2015-8779). Please review the CVEs referenced below for additional vulnerabilities that had already been fixed in previous versions of sys-libs/glibc, for which we have not issued a GLSA before. Workaround ========== A number of mitigating factors for CVE-2015-7547 have been identified. Please review the upstream advisory and references below. Resolution ========== All GNU C Library users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.21-r2" It is important to ensure that no running process uses the old glibc anymore. The easiest way to achieve that is by rebooting the machine after updating the sys-libs/glibc package. Note: Should you run into compilation failures while updating, please see bug 574948.
