Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access that is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and denial of service. This may be exploitable when a victim opens a specially crafted PDF file.
A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
An issue was discovered in fs/f2fs/super.c in the Linux kernel through 4.17.3, which does not properly validate secs_per_zone in a corrupted f2fs image, as demonstrated by a divide-by-zero error.
A flaw was found in ImageMagick in coders/jp2.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat from this vulnerability is to system availability.

An improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c in FFmpeg 2.8 and 4.0 may trigger an assertion violation while converting a crafted AVI file to MPEG4, leading to a denial of service.
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.
The CPDF_DIBSource::CreateDecoder function in core/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp in PDFium, as used in Google Chrome before 51.0.2704.63, mishandles decoder-initialization failure, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted PDF document.

In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well.
libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.

Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results.
An issue was discovered in WavPack 5.1.0 and earlier for W64 input. Out-of-bounds writes can occur because ParseWave64HeaderConfig in wave64.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.
In Artifex MuPDF 1.12.0 and earlier, multiple reachable assertions in the PDF parser allow an attacker to cause a denial of service (assert crash) via a crafted file.

clamscan in ClamAV before 0.99.4 contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause an out-of-bounds read when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition. This concerns pdf_parse_array and pdf_parse_string in libclamav/pdfng.c. Cisco Bug IDs: CSCvh91380, CSCvh91400.
