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.

In PoDoFo 0.9.5, there exists a heap-based buffer over-read vulnerability in UnescapeName() in PdfName.cpp. Remote attackers could leverage this vulnerability to cause a denial-of-service or possibly unspecified other impact via a crafted pdf file.

There is a heap-based buffer over-read in the getString function of util/decompile.c in libming 0.4.8 for CONSTANT8 data. A Crafted input will lead to a denial of service attack.

There is a heap-based buffer over-read in the getName function of util/decompile.c in libming 0.4.8 for CONSTANT16 data. A crafted input will lead to a denial of service or possibly unspecified other impact.

QEMU: cirrus: OOB access when updating VGA display

Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.

A CWE-125: Out-of-bounds Read vulnerability exists in all versions of the Modicon M580, Modicon M340, Modicon Quantum, and Modicon Premium which could cause the disclosure of unexpected data from the controller when reading specific memory blocks in the controller over Modbus.

A CWE-248: Uncaught Exception vulnerability exists in all versions of the Modicon M580, Modicon M340, Modicon Quantum, and Modicon Premium which could cause denial of service when reading memory blocks with an invalid data size or with an invalid data offset in the controller over Modbus.

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.

exempi: Stack-based buffer overflow in XMPFiles/source/FileHandlers/PostScript_Handler.cpp:PostScript_MetaHandler::ParsePSFile() allows for denial of service

An issue was discovered in Exempi through 2.4.4. There is a stack-based buffer over-read in the PostScript_MetaHandler::ParsePSFile() function in XMPFiles/source/FileHandlers/PostScript_Handler.cpp.

exempi: Heap-based buffer overflow in third-party/zuid/interfaces/MD5.cpp:MD5Update() allows for denial of service via crafted TIFF image

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FileHandlers/TIFF_Handler.cpp mishandles a case of a zero length, leading to a heap-based buffer over-read in the MD5Update() function in third-party/zuid/interfaces/MD5.cpp.

An issue was discovered in CImg v.220. A heap-based buffer over-read in load_bmp in CImg.h occurs when loading a crafted bmp image, a different vulnerability than CVE-2018-7588. This is in a "32 bits colors" case, aka case 32.

An issue was discovered in CImg v.220. A heap-based buffer over-read in load_bmp in CImg.h occurs when loading a crafted bmp image, a different vulnerability than CVE-2018-7588. This is in a Monochrome case, aka case 1.

An issue was discovered in CImg v.220. A heap-based buffer over-read in load_bmp in CImg.h occurs when loading a crafted bmp image, a different vulnerability than CVE-2018-7588. This is in a "16 bits colors" case, aka case 16.

An issue was discovered in CImg v.220. A heap-based buffer over-read in load_bmp in CImg.h occurs when loading a crafted bmp image, a different vulnerability than CVE-2018-7588. This is in a "256 colors" case, aka case 8.

php: Stack-based buffer under-read in php_stream_url_wrap_http_ex() in http_fopen_wrapper.c when parsing HTTP response

In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string.

The decode_init function in libavcodec/utvideodec.c in FFmpeg 2.8 through 3.4.2 allows remote attackers to cause a denial of service (Out of array read) via an AVI file with crafted dimensions within chroma subsampling data.

QEMU: i386: multiboot OOB access while loading kernel image

The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
