CVE-2017-1000116 [CRITICAL] CWE-78 CVE-2017-1000116: Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shel Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.

CVE-2017-15041 [CRITICAL] CVE-2017-15041: Go before 1.8.4 and 1.9.x before 1.9.1 allows "go get" remote command execution. Using custom domain Go before 1.8.4 and 1.9.x before 1.9.1 allows "go get" remote command execution. Using custom domains, it is possible to arrange things so that example.com/pkg1 points to a Subversion repository but example.com/pkg1/pkg2 points to a Git repository. If the Subversion repository includes a Git checkout in its pkg2 directory and some other work is done to en

CVE-2017-1000111 [HIGH] CVE-2017-1000111: Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously dis Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue

CVE-2017-1000115 [HIGH] CWE-59 CVE-2017-1000115: Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositor Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositories to modify files outside the repository
