ghostscript: incorrect access checking in temp file handling to disclose contents of files (699658)

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect access checking in temp file handling to disclose contents of files on the system otherwise not readable.

Matrix Synapse before 0.33.3.1 allows remote attackers to spoof events and possibly have unspecified other impacts by leveraging improper transaction and event signature validation.

ghostscript: setcolor missing type check (699655)

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the setcolor function to crash the interpreter or possibly have unspecified other impact.

ghostscript: missing type check in type checker (699659)

An issue was discovered in Artifex Ghostscript before 9.24. A type confusion in "ztype" could be used by remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.

ghostscript: /invalidaccess bypass after failed restore (699654)

An issue was discovered in Artifex Ghostscript before 9.24. Incorrect "restoration of privilege" checking during handling of /invalidaccess exceptions could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction.

nodejs-cached-path-relative: prototype pollution due to injected properties on Object.prototype

A prototype pollution attack in cached-path-relative versions <=1.0.1 allows an attacker to inject properties on Object.prototype which are then inherited by all the JS objects through the prototype chain causing a DoS attack.

rubygem-rack: Cross-site scripting (XSS) via `scheme` method on `Rack::Request`

There is a possible XSS vulnerability in Rack before 2.0.6 and 1.6.11. Carefully crafted requests can impact the data returned by the `scheme` method on `Rack::Request`. Applications that expect the scheme to be limited to 'http' or 'https' and do not escape the return value could be vulnerable to an XSS attack. Note that applications using the normal escaping mechanisms provided by Rails may not impacted, but applications that bypass the escaping mechanisms, or do not use them may be vulnerable.

rubygem-loofah: XXS when a crafted SVG element is republished

In the Loofah gem for Ruby, through v2.2.2, unsanitized JavaScript may occur in sanitized output when a crafted SVG element is republished.

lcms2: Integer overflow in AllocateDataSet() in cmscgats.c leading to heap-based buffer overflow

Little CMS (aka Little Color Management System) 2.9 has an integer overflow in the AllocateDataSet function in cmscgats.c, leading to a heap-based buffer overflow in the SetData function via a crafted file in the second argument to cmsIT8LoadFromFile.

GNU Libextractor through 1.7 has an out-of-bounds read vulnerability in EXTRACTOR_zip_extract_method() in zip_extractor.c.

elfutils: Double-free due to double decompression of sections in crafted ELF causes crash

libelf/elf_end.c in elfutils 0.173 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact because it tries to decompress twice.

ruby: Tainted flags are not propagated in Array#pack and String#unpack with some directives

An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats.

ruby: OpenSSL::X509:: Name equality check does not work correctly

An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.

exiv2: heap-based buffer over-read via a crafted image file

Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999.

libtiff: Heap-based buffer overflow in ChopUpSingleUncompressedStrip in tif_dirread.c

newoffsets handling in ChopUpSingleUncompressedStrip in tif_dirread.c in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file, as demonstrated by tiff2pdf. This is a different vulnerability than CVE-2018-15209.

kernel: incorrect bounds checking in yurex_read in drivers/usb/misc/yurex.c

An issue was discovered in yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7. Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges.

tcpdump: Buffer over-read in dccp_print_option() function in print-dccp.c

The DCCP parser in tcpdump before 4.9.3 has a buffer over-read in print-dccp.c:dccp_print_option().

tcpdump: Buffer over-read in print-802_11.c

The IEEE 802.11 parser in tcpdump before 4.9.3 has a buffer over-read in print-802_11.c for the Mesh Flags subfield.

chromium-browser: Out of bounds write in Mojo

Missing validation in Mojo in Google Chrome prior to 69.0.3497.81 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page.

chromium-browser: Out of bounds read in WebAudio

A use after free in WebAudio in Google Chrome prior to 69.0.3497.81 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
