etc/ObjectList in Metview 4.7.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a third party has indicated that the code to access this environment variable is not enabled in the shipped product

tools/url_handler.pl in TIN 2.4.1 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a third party has reported that this is intentional behavior, because the documentation states "url_handler.pl was designed to work together with tin which only issues shell escaped absolute URLs.

delphi_gui/WWWBrowserRunnerDM.pas in PasDoc 0.14 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a software maintainer has indicated that the code referencing the BROWSER environment variable is never used

exiv2: Heap-based buffer over-read in PngChunk::keyTXTChunk function of pngchunk_int.cpp

There is a heap-based buffer over-read in the Exiv2::Internal::PngChunk::keyTXTChunk function of pngchunk_int.cpp in Exiv2 0.26. A crafted PNG file will lead to a remote denial of service attack.

In VideoLAN VLC media player through 2.2.8, there is a type conversion vulnerability in modules/demux/mp4/libmp4.c in the MP4 demux module leading to a invalid free, because the type of a box may be changed between a read operation and a free operation.

ImageMagick: Resource exhaustion in ExtractPostscript function in coders/wpg.c

In ImageMagick 7.0.7-12 Q16, a large loop vulnerability was found in the function ExtractPostscript in coders/wpg.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted wpg image file that triggers a ReadWPGImage call.

kernel: kvm: stack-based out-of-bounds read via vmcall instruction

The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h.

opencv: Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp

OpenCV 3.3.1 has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp, because an incorrect size value is used.

In GraphicsMagick 1.3.27a, there is a heap-based buffer over-read in ReadOneJNGImage in coders/png.c, related to oFFs chunk allocation.

In GraphicsMagick 1.3.27a, there is a buffer over-read in ReadPALMImage in coders/palm.c when QuantumDepth is 8.

gimp: Heap-based buffer over-read in load_image function in plug-ins/common/file-gbr.c

In GIMP 2.8.22, there is a heap-based buffer over-read in load_image in plug-ins/common/file-gbr.c in the gbr import parser, related to mishandling of UTF-8 data.

gimp: Heap-based buffer overflow in the fli_read_brun function in plug-ins/file-fli/fli.c

In GIMP 2.8.22, there is a heap-based buffer overflow in the fli_read_brun function in plug-ins/file-fli/fli.c.

gimp: Heap-based buffer over-read in ReadImage function in plug-ins/common/file-tga.c

In GIMP 2.8.22, there is a heap-based buffer over-read in ReadImage in plug-ins/common/file-tga.c (related to bgr2rgb.part.1) via an unexpected bits-per-pixel value for an RGBA image.

gimp: Heap-based buffer over-read in read_creator_block function in plug-ins/common/file-psp.c

In GIMP 2.8.22, there is a heap-based buffer over-read in read_creator_block in plug-ins/common/file-psp.c.

gimp: Stack-based buffer over-read in xcf_load_stream function in app/xcf/xcf.c

In GIMP 2.8.22, there is a stack-based buffer over-read in xcf_load_stream in app/xcf/xcf.c when there is no '\0' character after the version string.

gimp: Heap-based buffer overflow in read_channel_data function in plug-ins/common/file-psp.c

In GIMP 2.8.22, there is a heap-based buffer overflow in read_channel_data in plug-ins/common/file-psp.c.

kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service

The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.

kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

An issue was discovered in Enigmail before 1.9.9 that allows remote attackers to trigger use of an intended public key for encryption, because incorrect regular expressions are used for extraction of an e-mail address from a comma-separated list, as demonstrated by a modified Full Name field and a homograph attack, aka TBE-01-002.

An issue was discovered in Enigmail before 1.9.9. A remote attacker can obtain cleartext content by sending an encrypted data block (that the attacker cannot directly decrypt) to a victim, and relying on the victim to automatically decrypt that block and then send it back to the attacker as quoted text, aka the TBE-01-005 "replay" issue.
