CVE-2019-6111 [MEDIUM] CWE-22 CVE-2019-6111: An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, t An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker

CVE-2018-1000001 [HIGH] CWE-787 CVE-2018-1000001: In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be use In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.

CVE-2015-3636 [MEDIUM] CVE-2015-3636: The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a c The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_I

CVE-2016-0728 [HIGH] CVE-2016-0728: The join_session_keyring function in security/keys/process_keys.c in the Linux kernel before 4.4.1 m The join_session_keyring function in security/keys/process_keys.c in the Linux kernel before 4.4.1 mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service (integer overflow and use-after-free) via crafted keyctl commands.

CVE-2010-3437 [MEDIUM] CWE-476 CVE-2010-3437: Integer signedness error in the pkt_find_dev_from_minor function in drivers/block/pktcdvd.c in the L Integer signedness error in the pkt_find_dev_from_minor function in drivers/block/pktcdvd.c in the Linux kernel before 2.6.36-rc6 allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and system crash) via a crafted index value in a PKT_CTRL_CMD_STATUS ioctl call.

CVE-2009-2698 [HIGH] CWE-476 CVE-2009-2698: The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in t The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket.

CVE-2009-3547 [HIGH] CWE-362 CVE-2009-3547: Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cau Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.
