This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container. CVE-2016-9962 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate 4.1 AV:L/AC:M/Au:S/C:P/I:P/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2016-9962.html CVE-2016-9962 https://bugzilla.suse.com/1012568 SUSE Bug 1012568 https://bugzilla.suse.com/1173425 SUSE Bug 1173425 In Go before 1.10.6 and 1.11.x before 1.11.3, the "go get" command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). Using custom domains, it's possible to arrange things so that a Git repository is cloned to a folder named ".git" by using a vanity import path that ends with "/.git". If the Git repository root contains a "HEAD" file, a "config" file, an "objects" directory, a "refs" directory, with some work to ensure the proper ordering of operations, "go get -u" can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the "config" file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running "go get -u". CVE-2018-16873 openSUSE Tumbleweed:runc-1.0.2-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2018-16873.html CVE-2018-16873 https://bugzilla.suse.com/1118897 SUSE Bug 1118897 https://bugzilla.suse.com/1118898 SUSE Bug 1118898 https://bugzilla.suse.com/1118899 SUSE Bug 1118899 In Go before 1.10.6 and 1.11.x before 1.11.3, the "go get" command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (both '{' and '}' characters). Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). The attacker can cause an arbitrary filesystem write, which can lead to code execution. CVE-2018-16874 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2018-16874.html CVE-2018-16874 https://bugzilla.suse.com/1118897 SUSE Bug 1118897 https://bugzilla.suse.com/1118898 SUSE Bug 1118898 https://bugzilla.suse.com/1118899 SUSE Bug 1118899 The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected. CVE-2018-16875 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2018-16875.html CVE-2018-16875 https://bugzilla.suse.com/1118897 SUSE Bug 1118897 https://bugzilla.suse.com/1118898 SUSE Bug 1118898 https://bugzilla.suse.com/1118899 SUSE Bug 1118899 runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory. CVE-2019-16884 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2019-16884.html CVE-2019-16884 https://bugzilla.suse.com/1152308 SUSE Bug 1152308 runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.) CVE-2019-19921 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2019-19921.html CVE-2019-19921 https://bugzilla.suse.com/1160452 SUSE Bug 1160452 https://bugzilla.suse.com/1208962 SUSE Bug 1208962 runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe. CVE-2019-5736 openSUSE Tumbleweed:runc-1.0.2-1.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2019-5736.html CVE-2019-5736 https://bugzilla.suse.com/1121967 SUSE Bug 1121967 https://bugzilla.suse.com/1122185 SUSE Bug 1122185 https://bugzilla.suse.com/1173421 SUSE Bug 1173421 https://bugzilla.suse.com/1218894 SUSE Bug 1218894 runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race condition. CVE-2021-30465 openSUSE Tumbleweed:runc-1.0.2-1.2 moderate To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2021-30465.html CVE-2021-30465 https://bugzilla.suse.com/1185405 SUSE Bug 1185405 https://bugzilla.suse.com/1189161 SUSE Bug 1189161
