libgit2: denial of service (DoS) via crafted repository index files

Integer overflow in the index.c:read_entry() function while decompressing a compressed prefix length in libgit2 before v0.26.2 allows an attacker to cause a denial of service (out-of-bounds read) via a crafted repository index file.

exempi: Heap-based buffer overflow in PSD_MetaHandler::CacheFileData function in XMPFiles/source/FormatSupport/PSIR_FileWriter.cpp allows for denial of service via crafted XLS file

An issue was discovered in Exempi through 2.4.4. A certain case of a 0xffffffff length is mishandled in XMPFiles/source/FormatSupport/PSIR_FileWriter.cpp, leading to a heap-based buffer over-read in the PSD_MetaHandler::CacheFileData() function.

binutils: Integer overflow in the display_debug_ranges function resulting in crash

The display_debug_ranges function in dwarf.c in GNU Binutils 2.30 allows remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact via a crafted ELF file, as demonstrated by objdump.

Google TensorFlow 1.7.x and earlier is affected by a Buffer Overflow vulnerability. The type of exploitation is context-dependent.

binutils: integer underflow or overflow via an ELF file with a corrupt DWARF FORM block in libbfd library

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer underflow or overflow, and application crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm.

binutils: integer overflow via an ELF file with corrupt dwarf1 debug information in libbfd library

The parse_die function in dwarf1.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer overflow and application crash) via an ELF file with corrupt dwarf1 debug information, as demonstrated by nm.

KingView 7.5SP1 has an integer overflow during stgopenstorage API read operations.

libvncserver: integer overflow in vcSetXCutTextProc in VNConsole.c

An issue was discovered in vcSetXCutTextProc() in VNConsole.c in LinuxVNC and VNCommand from the LibVNC/vncterm distribution through 0.9.10. Missing sanitization of the client-specified message length may cause integer overflow or possibly have unspecified other impact via a specially crafted VNC packet.

libvncserver: Improper input sanitization in rfbProcessClientNormalMessage in rfbserver.c

An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets.

Integer format vulnerability in the ticket number generator in Enhancesoft osTicket before 1.10.2 allows remote attackers to cause a denial-of-service (preventing the creation of new tickets) via a large number of digits in the ticket number format setting.

VMware Workstation (15.x before 15.0.2 and 14.x before 14.1.5) and Fusion (11.x before 11.0.2 and 10.x before 10.1.5) contain an integer overflow vulnerability in the virtual network devices. This issue may allow a guest to execute code on the host.

kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact

The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value.

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Unprivileged users may be able to access privileged kernel data.

glibc: integer overflow in malloc functions

The malloc implementation in the GNU C Library (aka glibc or libc6), from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZE_MAX and could return a pointer to a heap region that is smaller than requested, eventually leading to heap corruption.

binutils: integer overflow in load_specific_debug_section function in objdump.c

In GNU Binutils 2.30, there's an integer overflow in the function load_specific_debug_section() in objdump.c, which results in `malloc()` with 0 size. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

glibc: Integer overflow in posix_memalign in memalign functions

An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.

binutils: Integer overflow in elf_object_p function in elfcode.h

The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

The outputSWF_TEXT_RECORD function (util/outputscript.c) in libming through 0.4.8 is vulnerable to an integer overflow and resultant out-of-bounds read, which may allow attackers to cause a denial of service or unspecified other impact via a crafted SWF file.

The js_strtod function in jsdtoa.c in Artifex MuJS through 1.0.2 has an integer overflow because of incorrect exponent validation.

chromium-browser: Integer overflow in SwiftShader

Integer overflows in Swiftshader in Google Chrome prior to 68.0.3440.75 potentially allowed a remote attacker to execute arbitrary code via a crafted HTML page.
