The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.1.1a (Affected 1.1.1).

Spark's Apache Maven-based build includes a convenience script, 'build/mvn', that downloads and runs a zinc server to speed up compilation. It has been included in release branches since 1.3.x, up to and including master. This server will accept connections from external hosts by default. A specially-crafted request to the zinc server could cause it to reveal information in files readable to the developer account running the build. Note that this issue does not affect end users of Spark, only developers building Spark from source code.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Parser). Supported versions that are affected are 5.5.61 and prior, 5.6.41 and prior, 5.7.23 and prior and 8.0.12 and prior. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Python Cryptographic Authority pyopenssl version prior to version 17.5.0 contains a CWE-416: Use After Free vulnerability in X509 object handling that can result in Use after free can lead to possible denial of service or remote code execution.. This attack appear to be exploitable via Depends on the calling application and if it retains a reference to the memory.. This vulnerability appears to have been fixed in 17.5.0.

An exploitable stack-based buffer overflow vulnerability exists in the retrieval of a database field in video-core's HTTP server of Samsung SmartThings Hub. The video-core process insecurely extracts the shard.videoHostURL field from its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.

An exploitable buffer overflow vulnerability exists in the /cameras/XXXX/clips handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250-Firmware version 0.20.17. The strncpy call overflows the destination buffer, which has a size of 52 bytes. An attacker can send an arbitrarily long "startTime" value in order to exploit this vulnerability.

An exploitable buffer overflow vulnerability exists in the credentials handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250-Firmware version 0.20.17. The strncpy overflows the destination buffer, which has a size of 64 bytes. An attacker can send an arbitrarily long "bucket" value in order to exploit this vulnerability.

An exploitable buffer overflow vulnerability exists in the Samsung WifiScan handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long "cameraIp" value in order to exploit this vulnerability.

Insufficient security checks exist in the recovery procedure used by the Foscam C1 Indoor HD Camera running application firmware 2.52.2.43. A HTTP request can allow for a user to perform a firmware upgrade using a crafted image. Before any firmware upgrades in this image are flashed to the device, binaries as well as arguments to shell commands contained in the image are executed with elevated privileges.
