Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments.

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: posix_spawn_file_actions_addopen fails to copy the path argument (CVE-2014-4043)

  - glibc: heap/stack gap jumping via unbounded stack allocations (CVE-2017-1000366)

  - ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token     when RPATH is composed entirely of this token, which might allow local users to gain privileges by     creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH     value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a     different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard     operating-system distribution would ship an applicable setuid or setgid program. (CVE-2011-1658)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

An updated rhev-hypervisor5 package that fixes three security issues and one bug is now available.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

A flaw was found in the way libtasn1 decoded DER data. An attacker could create a carefully-crafted X.509 certificate that, when parsed by an application that uses GnuTLS, could cause the application to crash. (CVE-2012-1569)

A flaw was found in the way GnuTLS decrypted malformed TLS records.
This could cause a TLS/SSL client or server to crash when processing a specially crafted TLS record from a remote TLS/SSL connection peer.
(CVE-2012-1573)

An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort.
(CVE-2012-0864)

Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting CVE-2012-1569 and CVE-2012-1573.

  - A out-of-bounds memory error exists in OpenSSL that     allows a remote attacker to cause a denial of service or     possibly obtain sensitive information by using a     malformed ClientHello handshake message. This is also     known as the 'OCSP stapling vulnerability'.
    (CVE-2011-0014)

  - A flaw exists in the addmntent() function in the glibc     library due to a failure to report the error status for     failed attempts to write to the /etc/mtab file. A local     attacker can exploit this to corrupt the file by using     writes from a process with a small RLIMIT_FSIZE value.
    (CVE-2011-1089)

  - A flaw exists in the png_set_text_2() function in the     file pngset.c in the libpng library due to a failure to     properly allocate memory. An unauthenticated, remote     attacker can exploit this, via a crafted text chunk in a     PNG image file, to trigger a heap-based buffer overflow,     resulting in denial of service or the execution of     arbitrary code. (CVE-2011-3048)

  - A flaw exists in the DTLS implementation in OpenSSL due     to performing a MAC check only if certain padding is     valid. A remote attacker can exploit this, via a padding     oracle attack, to recover the plaintext. (CVE-2011-4108)

  - A double-free error exists in OpenSSL when the     X509_V_FLAG_POLICY_CHECK is enabled. A remote attacker     can exploit this by triggering a policy check failure,     resulting in an unspecified impact. (CVE-2011-4109)

  - A flaw exists in OpenSSL in the SSL 3.0 implementation     due to improper initialization of data structures used     for block cipher padding. A remote attacker can exploit     this, by decrypting the padding data sent by an SSL     peer, to obtain sensitive information. (CVE-2011-4576)

  - A denial of service vulnerability exists in OpenSSL when     RFC 3779 support is enabled. A remote attacker can     exploit this to cause an assertion failure, by using an     X.509 certificate containing certificate extension data     associated with IP address blocks or Autonomous System     (AS) identifiers. (CVE-2011-4577)

  - A denial of service vulnerability exists in the RPC     implementation in the glibc library due to a flaw in the     svc_run() function. A remote attacker can exploit this,     via large number of RPC connections, to exhaust CPU     resources. (CVE-2011-4609)

  - A denial of service vulnerability exists in the Server     Gated Cryptography (SGC) implementation in OpenSSL due     to a failure to properly handle handshake restarts. A     remote attacker can exploit this, via unspecified     vectors, to exhaust CPU resources. (CVE-2011-4619)

  - A denial of service vulnerability exists in OpenSSL due     to improper support of DTLS applications. A remote     attacker can exploit this, via unspecified vectors     related to an out-of-bounds read error. Note that this     vulnerability exists because of an incorrect fix for     CVE-2011-4108. (CVE-2012-0050)

  - A security bypass vulnerability exists in the glibc     library due to an integer overflow condition in the     vfprintf() function in file stdio-common/vfprintf.c. An     attacker can exploit this, by using a large number of     arguments, to bypass the FORTIFY_SOURCE protection     mechanism, allowing format string attacks or writing to     arbitrary memory. (CVE-2012-0864)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string that uses positional parameters and     many format specifiers, to bypass the FORTIFY_SOURCE     format-string protection mechanism, thus causing stack     corruption and a crash. (CVE-2012-3404)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string with a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering desynchronization     within the buffer size handling, resulting in a     segmentation fault and crash. (CVE-2012-3405)

  - A flaw exists in the glibc library in the vfprintf()     function in file stdio-common/vfprintf.c due to a     failure to properly restrict the use of the alloca()     function when allocating the SPECS array. An attacker     can exploit this, via a crafted format string using     positional parameters and a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering a denial of     service or the possible execution of arbitrary code.
    (CVE-2012-3406)

  - A flaw exists in the glibc library due to multiple     integer overflow conditions in the strtod(), strtof(),     strtold(), strtod_l(), and other unspecified related     functions. A local attacker can exploit these to trigger     a stack-based buffer overflow, resulting in an     application crash or the possible execution of arbitrary     code. (CVE-2012-3480)

  - A privilege escalation vulnerability exists in the     Virtual Machine Communication Interface (VMCI) due to a     failure by control code to properly restrict memory     allocation. A local attacker can exploit this, via     unspecified vectors, to gain privileges. (CVE-2013-1406)

  - An error exists in the implementation of the Network     File Copy (NFC) protocol. A man-in-the-middle attacker     can exploit this, by modifying the client-server data     stream, to cause a denial of service or the execution     of arbitrary code. (CVE-2013-1659)

An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort.

   VMware would like to thank Alexander Minozhenko from ERPScan for    reporting this issue to us.

The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort.
(CVE-2012-0864)

All users of glibc are advised to upgrade to these updated packages, which contain a patch to resolve this issue.

(CVE-2012-0864)

This update also fixes the following bugs :

  - Previously, the dynamic loader generated an incorrect     ordering for initialization according to the ELF     specification. This could result in incorrect ordering     of DSO constructors and destructors. With this update,     dependency resolution has been fixed.

  - Previously, locking of the main malloc arena was     incorrect in the retry path. This could result in a     deadlock if an sbrk request failed. With this update,     locking of the main arena in the retry path has been     fixed. This issue was exposed by a bug fix provided in a     previous update.

  - Calling memcpy with overlapping arguments on certain     processors would generate unexpected results. While such     code is a clear violation of ANSI/ISO standards, this     update restores prior memcpy behavior.

All users of glibc are advised to upgrade to these updated packages, which contain patches to resolve these issues.

  - glibc: FORTIFY_SOURCE format string protection bypass via nargs integer overflow (CVE-2012-0864)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It was discovered that the GNU C Library did not properly handle integer overflows in the timezone handling code. An attacker could use this to possibly execute arbitrary code by convincing an application to load a maliciously constructed tzfile. (CVE-2009-5029)

It was discovered that the GNU C Library did not properly handle passwd.adjunct.byname map entries in the Network Information Service (NIS) code in the name service caching daemon (nscd). An attacker could use this to obtain the encrypted passwords of NIS accounts. This issue only affected Ubuntu 8.04 LTS. (CVE-2010-0015)

Chris Evans reported that the GNU C Library did not properly calculate the amount of memory to allocate in the fnmatch() code. An attacker could use this to cause a denial of service or possibly execute arbitrary code via a maliciously crafted UTF-8 string. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 10.10.
(CVE-2011-1071)

Tomas Hoger reported that an additional integer overflow was possible in the GNU C Library fnmatch() code.

This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 10.10.
(CVE-2011-1095)

It was discovered that the GNU C library loader expanded the $ORIGIN dynamic string token when RPATH is composed entirely of this token.
This could allow an attacker to gain privilege via a setuid program that had this RPATH value. (CVE-2011-1658)

It was discovered that the GNU C library implementation of memcpy optimized for Supplemental Streaming SIMD Extensions 3 (SSSE3) contained a possible integer overflow. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 10.04 LTS. (CVE-2011-2702)

John Zimmerman discovered that the Remote Procedure Call (RPC) implementation in the GNU C Library did not properly handle large numbers of connections. This could allow a remote attacker to cause a denial of service. (CVE-2011-4609)

It was discovered that the GNU C Library vfprintf() implementation contained a possible integer overflow in the format string protection code offered by FORTIFY_SOURCE. An attacker could use this flaw in conjunction with a format string vulnerability to bypass the format string protection and possibly execute arbitrary code. (CVE-2012-0864).
