MDVSA-2015:171: freerdp

Updated freerdp packages fix security vulnerabilities:

Integer overflows in memory allocations in client/X11/xf_graphics.c in
FreeRDP through 1.0.2 allows remote RDP servers to have an unspecified
impact through unspecified vectors (CVE-2014-0250).

Integer overflow in the license_read_scope_list function in
libfreerdp/core/license.c in FreeRDP through 1.0.2 allows remote RDP
servers to cause a denial of service (application crash) or possibly
have unspecified other impact via a large ScopeCount value in a Scope
List in a Server License Request packet (CVE-2014-0791).

MDVSA-2015:170: gcc

Updated gcc packages fix the following security issue:

Multiple integer overflow issues were found in libgfortran, the
run-time support library for the Fortran compiler. These could possibly
be used to crash a Fortran application or cause it to execute arbitrary
code CVE-2014-5044).

They also fix the following bugs:

The gcc rtl-optimization sched2 miscompiles syscall sequence wich
can cause random panic in glibc and kernel (gcc/PR61801)

clang++ fails to find cxxabi.h and cxxabi_tweaks.h during build
(mga#13543)

MDVSA-2015:169: git

Updated git packages fix security vulnerability:

It was reported that git, when used as a client on a case-insensitive
filesystem, could allow the overwrite of the .git/config file when
the client performed a git pull. Because git permitted committing
.Git/config (or any case variation), on the pull this would replace the
user’s .git/config. If this malicious config file contained defined
external commands (such as for invoking and editor or an external diff
utility) it could allow for the execution of arbitrary code with the
privileges of the user running the git client (CVE-2014-9390).

MDVSA-2015:168: glibc

Updated glibc packages fix security vulnerabilities:

Stephane Chazelas discovered that directory traversal issue in locale
handling in glibc. glibc accepts relative paths with .. components
in the LC_* and LANG variables. Together with typical OpenSSH
configurations (with suitable AcceptEnv settings in sshd_config),
this could conceivably be used to bypass ForceCommand restrictions
(or restricted shells), assuming the attacker has sufficient level
of access to a file system location on the host to create crafted
locale definitions there (CVE-2014-0475).

David Reid, Glyph Lefkowitz, and Alex Gaynor discovered a bug where
posix_spawn_file_actions_addopen fails to copy the path argument
(glibc bz #17048) which can, in conjunction with many common memory
management techniques from an application, lead to a use after free,
or other vulnerabilities (CVE-2014-4043).

This update also fixes the following issues: x86: Disable x87 inline
functions for SSE2 math (glibc bz #16510) malloc: Fix race in free()
of fastbin chunk (glibc bz #15073)

Tavis Ormandy discovered a heap-based buffer overflow in the
transliteration module loading code. As a result, an attacker who can
supply a crafted destination character set argument to iconv-related
character conversation functions could achieve arbitrary code
execution.

This update removes support of loadable gconv transliteration
modules. Besides the security vulnerability, the module loading code
had functionality defects which prevented it from working for the
intended purpose (CVE-2014-5119).

Adhemerval Zanella Netto discovered out-of-bounds reads in additional
code page decoding functions (IBM933, IBM935, IBM937, IBM939, IBM1364)
that can be used to crash the systems, causing a denial of service
conditions (CVE-2014-6040).

The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of “$((… ))”
where “…” can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass the
WRDE_NOCMD flag. This update fixes the issue (CVE-2014-7817).

The vfprintf function in stdio-common/vfprintf.c in GNU C Library
(aka glibc) 2.5, 2.12, and probably other versions does not properly
restrict the use of the alloca function when allocating the SPECS
array, which allows context-dependent attackers to bypass the
FORTIFY_SOURCE format-string protection mechanism and cause a denial
of service (crash) or possibly execute arbitrary code via a crafted
format string using positional parameters and a large number of format
specifiers (CVE-2012-3406).

The nss_dns implementation of getnetbyname could run into an infinite
loop if the DNS response contained a PTR record of an unexpected format
(CVE-2014-9402).

Also glibc lock elision (new feature in glibc 2.18) has been disabled
as it can break glibc at runtime on newer Intel hardware (due to
hardware bug)

Under certain conditions wscanf can allocate too little memory
for the to-be-scanned arguments and overflow the allocated buffer
(CVE-2015-1472).

The incorrect use of “__libc_use_alloca (newsize)” caused a different
(and weaker) policy to be enforced which could allow a denial of
service attack (CVE-2015-1473).

MDVSA-2015:167: glpi

Updated glpi package fixes security vulnerabilities:

Due to a bug in GLPI before 0.84.7, a user without access to cost
information can in fact see the information when selecting cost as
a search criteria (CVE-2014-5032).

An issue in GLPI before 0.84.8 may allow arbitrary local files to be
included by PHP through an autoload function (CVE-2014-8360).

SQL injection vulnerability in ajax/getDropdownValue.php in GLPI
before 0.85.1 allows remote authenticated users to execute arbitrary
SQL commands via the condition parameter (CVE-2014-9258).
