openssh: Improper write operations in readonly mode allow for zero-length file creation

The processopen function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files...

USN-3620-1 linux vulnerabilities

It was discovered that the netlink 802.11 configuration interface in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker with the CAPNETADMIN privilege could use this to cause a denial of service system crash or possibly execute arbitrary code...

LibreSSL Information Disclosure Vulnerability

LibreSSL is a fork of the OpenSSL cryptographic software library developed by the OpenBSD project and an open source implementation of the Secure Sockets Layer SSL and Transport Layer Security TLS protocols. LibreSSL version 2.7.0 prior to 2.7.1 contains a security vulnerability in the...

CVE-2018-8970

The intx509paramsethosts function in lib/libcrypto/x509/x509vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain...

Exempi 'MD5Update()' function heap buffer overflow vulnerability

Exempi is an open source implementation of XMP based on the Adobe XMP SDK. A heap buffer overflow vulnerability exists in the 'MD5Update' function of the third-party/zuid/interfaces/MD5.cpp file in Exempi 2.4.4 and earlier, which stems from the XMPFiles/source/FileHandlers/TIFFHandler. The cpp fi...

DEBIAN-CVE-2018-7728

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FileHandlers/TIFFHandler.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...

OpenSSH: Permission issue

Background OpenSSH is a complete SSH protocol implementation that includes SFTP client and server support. Description The processopen function in sftp-server.c in OpenSSH did not properly prevent write operations in readonly mode. Impact A remote attacker could cause the creation of zero-length...

Updated openssh packages fix security vulnerability

It was found that the boundary checks in the code implementing support for pre-authentication compression could have been optimized out by certain compilers. An attacker able to compromise the privilege-separated process could possibly use this flaw for further attacks against the privileged...

Linux kernel denial of service vulnerability (CNVD-2017-37874)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A vulnerability exists in the Salsa20 encryption algorithm in versions of Linux kernel prior to 4.14.8, which arises from a program's failure to properly handle input ...

The vulnerability of the process_open function in the OpenSSH cryptographic protection mechanism allows a hacker to cause a service failure.

The vulnerability of the processopen function in sftp-server.c, a component of the OpenSSH cryptographic security tool, is related to an error in the “read-only” mode of operation. Exploiting this vulnerability could allow a malicious actor to cause service failures by creating files with zero...

DEBIAN-CVE-2017-17805

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 AFALG-based skcipher interface CONFIGCRYPTOUSERAPISKCIPHER to cause a denial of service uninitialized-memory free and kernel crash or have...
