-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:159 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : jasper Date : March 29, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated jasper packages fix security vulnerabilities: Josh Duart of the Google Security Team discovered heap-based buffer overflow flaws in JasPer, which could lead to denial of service (application crash) or the execution of arbitrary code (CVE-2014-9029). A double free flaw was found in the way JasPer parsed ICC color profiles in JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code (CVE-2014-8137). A heap-based buffer overflow flaw was
MDVSA-2015:119: x11-server
Updated x11-server packages fix security vulnerabilities:
Ilja van Sprundel of IOActive discovered several security issues in the
X.org X server, which may lead to privilege escalation or denial of
service (CVE-2014-8091, CVE-2014-8092, CVE-2014-8093, CVE-2014-8094,
CVE-2014-8095, CVE-2014-8096, CVE-2014-8097, CVE-2014-8098,
CVE-2014-8099, CVE-2014-8100, CVE-2014-8101, CVE-2014-8102).
Olivier Fourdan from Red Hat has discovered a protocol handling
issue in the way the X server code base handles the XkbSetGeometry
request, where the server trusts the client to send valid string
lengths. A malicious client with string lengths exceeding the
request length can cause the server to copy adjacent memory data
into the XKB structs. This data is then available to the client via
the XkbGetGeometry request. This can lead to information disclosure
issues, as well as possibly a denial of service if a similar request
can cause the server to crash (CVE-2015-0255).
MDVSA-2015:118: xlockmore
Updated xlockmore packages fix security vulnerability:
xlockmore before 5.45 contains a security flaw related to a bad value
of fnt for pyro2 which could cause an X error. This update backports
the fix for version 5.43.
MDVSA-2015:117: emacs
Updated emacs packages fix security vulnerabilities:
Steve Kemp discovered multiple temporary file handling issues in
Emacs. A local attacker could use these flaws to perform symbolic link
attacks against users running Emacs (CVE-2014-3421, CVE-2014-3422,
CVE-2014-3423, CVE-2014-3424).
MDVSA-2015:116: libtasn1
Updated libtasn1 packages fix security vulnerabilities:
Multiple buffer boundary check issues were discovered in libtasn1
library, causing it to read beyond the boundary of an allocated buffer.
An untrusted ASN.1 input could cause an application using the library
to crash (CVE-2014-3467).
It was discovered that libtasn1 library function asn1_get_bit_der()
could incorrectly report negative bit length of the value read from
ASN.1 input. This could possibly lead to an out of bounds access in
an application using libtasn1, for example in case if application
tried to terminate read value with NUL byte (CVE-2014-3468).
A NULL pointer dereference flaw was found in libtasn1’s
asn1_read_value_type() / asn1_read_value() function. If an application
called the function with a NULL value for an ivalue argument to
determine the amount of memory needed to store data to be read from
the ASN.1 input, libtasn1 could incorrectly attempt to dereference
the NULL pointer, causing an application using the library to crash
(CVE-2014-3469).
MDVSA-2015:115: libvirt
Updated libvirt packages fix security vulnerabilities:
The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through
1.2.1 allows local users to (1) delete arbitrary host devices
via the virDomainDeviceDettach API and a symlink attack on /dev
in the container; (2) create arbitrary nodes (mknod) via the
virDomainDeviceAttach API and a symlink attack on /dev in the
container; and cause a denial of service (shutdown or reboot host
OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a
symlink attack on /dev/initctl in the container, related to paths under
/proc//root and the virInitctlSetRunLevel function (CVE-2013-6456).
libvirt was patched to prevent expansion of entities when parsing XML
files. This vulnerability allowed malicious users to read arbitrary
files or cause a denial of service (CVE-2014-0179).
An out-of-bounds read flaw was found in the way libvirt’s
qemuDomainGetBlockIoTune() function looked up the disk index in
a non-persistent (live) disk configuration while a persistent disk
configuration was being indexed. A remote attacker able to establish a
read-only connection to libvirtd could use this flaw to crash libvirtd
or, potentially, leak memory from the libvirtd process (CVE-2014-3633).
A denial of service flaw was found in the way libvirt’s
virConnectListAllDomains() function computed the number of used
domains. A remote attacker able to establish a read-only connection
to libvirtd could use this flaw to make any domain operations within
libvirt unresponsive (CVE-2014-3657).
Eric Blake discovered that libvirt incorrectly handled permissions
when processing the qemuDomainFormatXML command. An attacker with
read-only privileges could possibly use this to gain access to certain
information from the domain xml file (CVE-2014-7823).
The qemuDomainMigratePerform and qemuDomainMigrateFinish2 functions
in qemu/qemu_driver.c in libvirt do not unlock the domain when an
ACL check fails, which allow local users to cause a denial of service
via unspecified vectors (CVE-2014-8136).
The XML getters for for save images and snapshots objects don’t
check ACLs for the VIR_DOMAIN_XML_SECURE flag and might possibly dump
security sensitive information. A remote attacker able to establish
a connection to libvirtd could use this flaw to cause leak certain
limited information from the domain xml file (CVE-2015-0236).
MDVSA-2015:114: cifs-utils
Updated cifs-utils packages fix security vulnerability:
Sebastian Krahmer discovered a stack-based buffer overflow flaw in
cifscreds.c (CVE-2014-2830).
MDVSA-2015:113: dovecot
Updated dovecot packages fix security vulnerability.
Dovecot before 2.2.13 is vulnerable to a DoS attack against
imap/pop3-login processes. If SSL/TLS handshake was started but
wasn’t finished, the login process attempted to eventually forcibly
disconnect the client, but failed to do it correctly. This could have
left the connections hanging around for a long time (CVE-2014-3430).
