A heap-based buffer overflow flaw was found in the SOCKS5 proxy handshake in the Curl package. If Curl is unable to resolve the address itself, it passes the hostname to the SOCKS5 proxy. However, the maximum length of the hostname that can be passed is 255 bytes. If the hostname is longer, then Curl switches to the local name resolving and passes the resolved address only to the proxy. The local ...
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.
The host is installed with Linux kernel and is prone to a TCP session hijack vulnerability. A flaw is present in the application, which fails to handle a blind in-window attack. Successful exploitation allows man-in-the-middle attackers to hijack TCP sessions.
The host is installed with MySQL 5.1.73 and earlier on OEL 6, mariadb 5.5.50 and earlier on OEL 7 or MySQL 5.0.95 and earlier on OEL 5 and is prone to a privilege escalation vulnerability. A flaw is present in the application, which fails to properly handle MySQL logging functions. Successful exploitation allows remote attackers to execute arbitrary code.
A flaw was found in OpenSSH in versions 5.7 through 8.3, where an Observable Discrepancy occurs and leads to an information leak in the algorithm negotiation. This flaw allows a man-in-the-middle attacker to target initial connection attempts, where there is no host key for the server that has been cached by the client.
A flaw was found in the scp program shipped with the openssh-clients package. An attacker having the ability to scp files to a remote server, could execute arbitrary commands on the remote server by including the command as a part of the filename being copied on the server. This command is run with the permissions of user with which the files were copied on the remote server. The highest threat fr ...
A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.
