DEBIAN-CVE-2019-15145

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack application crash via an out-of-bounds read by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::getdirectcontext in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h...

DjVuLibre Buffer Overflow Vulnerability (CNVD-2019-29361)

DjVuLibre is an open source implementation of DjVu computer file format that includes a DjVu file viewer, browser plug-in, DjVu file decoder/encoder and other utilities. A buffer overflow vulnerability exists in DjVuLibre version 3.5.27, which stems from a failure to perform zero-byte checking in...

openssl: 0-byte record padding oracle

If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received...

libssh2: Zero-byte allocation with a specially crafted SFTP packed leading to an out-of-bounds read

An out of bounds read flaw was discovered in libssh2 when a specially crafted SFTP packet is received from the server. A remote attacker who compromises a SSH server may be able to cause a denial of service or read data in the client memory...

Fedora 30 : libssh2 (2019-70a9d4f970)

This update addresses various overflow conditions that could result in possible memory read/write out of bounds errors or zero byte allocations when connected to a malicious server. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update...

CVE-2011-3151

The Ubuntu SELinux initscript before version 1:0.10 used touch to create a lockfile in a world-writable directory. If the OS kernel does not have symlink protections then an attacker can cause a zero byte file to be allocated on any writable filesystem...

Denial Of Service (DoS)

libssh2.so is vulnerable to denial of service. A malicious server is able to crash the process by sending a malicious SFTP packet with zero value for the payload length, causing zero-byte allocation that results in an out-of-bounds read...

libssh2 -- multiple issues

libssh2 developers report: Defend against possible integer overflows in compmethodzlibdecomp. Defend against writing beyond the end of the payload in libssh2transportread. Sanitize paddinglength - libssh2transportread. This prevents an underflow resulting in a potential out-of-bounds read if a...

DEBIAN-CVE-2018-12088

S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is...

Denial Of Service Through Stack Buffer Overflow

libiniparser.so is vulnerable to denial of service DoS through stack-base buffer overflow. The vulnerability exists in iniparserload of iniparser.c and occurs when parsing a zero-byte file, causing a denial of service DoS attack...
