Qemu: qcow1: validate L2 table size to avoid integer overflows

Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service (crash) via a large L2 table in a QCOW version 1 image.

Qemu: qcow1: validate image size to avoid out-of-bounds memory access

Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read.

freerdp: integer overflows in memory allocations in client/X11/xf_graphics.c

Multiple integer overflows in client/X11/xf_graphics.c in FreeRDP allow remote attackers to have an unspecified impact via the width and height to the (1) xf_Pointer_New or (2) xf_Bitmap_Decompress function, which causes an incorrect amount of memory to be allocated.

libpng: denial of service via png_push_read_chunk()

The png_push_read_chunk function in pngpread.c in the progressive decoder in libpng 1.6.x through 1.6.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an IDAT chunk with a length of zero.

Integer signedness error in Apple QuickTime before 7.7.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted stsz atom in a movie file.

Integer signedness error in CoreText in Apple OS X before 10.9.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Unicode font.

The ASF_ReadObject_file_properties function in modules/demux/asf/libasf.c in the ASF Demuxer in VideoLAN VLC Media Player before 2.1.3 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a zero minimum and maximum data packet size in an ASF file.

v8: numeric casting issues

Google V8, as used in Google Chrome before 34.0.1847.116, does not properly use numeric casts during handling of typed arrays, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JavaScript code.

Integer overflow in the SoftwareFrameManager::SwapToNewFrame function in content/browser/renderer_host/software_frame_manager.cc in the software compositor in Google Chrome before 34.0.1847.116 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger an attempted mapping of a large amount of renderer memory.

v8: memory corruption issue fixed in Google Chrome 34.0.1847.116

Google V8, as used in Google Chrome before 34.0.1847.116, does not properly implement lazy deoptimization, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted JavaScript code, as demonstrated by improper handling of a heap allocation of a number outside the Small Integer (aka smi) range.

Multiple integer overflows in the replace-data functionality in the CharacterData interface implementation in core/dom/CharacterData.cpp in Blink, as used in Google Chrome before 34.0.1847.137, allow remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to ranges.

Integer overflow in the AudioInputRendererHost::OnCreateStream function in content/browser/renderer_host/media/audio_input_renderer_host.cc in Google Chrome before 35.0.1916.114 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger a large shared-memory allocation.

Multiple off-by-one errors in Icinga, possibly 1.10.2 and earlier, allow remote attackers to cause a denial of service (crash) via unspecified vectors to the (1) display_nav_table, (2) print_export_link, (3) page_num_selector, or (4) page_limit_selector function in cgi/cgiutils.c or (5) status_page_num_selector function in cgi/status.c, which triggers a stack-based buffer overflow.

Off-by-one error in the bpf_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 3.1.8, when BPF JIT is enabled, allows local users to cause a denial of service (system crash) or possibly gain privileges via a long jump after a conditional jump.

QEMU: out of bounds buffer accesses, guest triggerable via IDE SMART

Off-by-one error in the cmd_smart function in the smart self test in hw/ide/core.c in QEMU before 2.0 allows local users to have unspecified impact via a SMART EXECUTE OFFLINE command that triggers a buffer underflow and memory corruption.

exim: local code execution via string expansion

expand.c in Exim before 4.83 expands mathematical comparisons twice, which allows local users to gain privileges and execute arbitrary commands via a crafted lookup value.

Multiple integer signedness errors in the Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 1.4.13 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers a stack-based buffer overflow.

krb5: buffer overrun in kadmind with LDAP backend (MITKRB5-SA-2014-001)

Off-by-one error in the krb5_encode_krbsecretkey function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) 1.6.x through 1.11.x before 1.11.6 and 1.12.x before 1.12.2 allows remote authenticated users to cause a denial of service (buffer overflow) or possibly execute arbitrary code via a series of "cpw -keepold" commands.

Integer overflow in CoreGraphics in Apple iOS before 8 and Apple TV before 7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF document.
