CVE-2019-6974 5 Canonical, Debian, F5 and 2 more 24 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 21 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free.
CVE-2019-6454 8 Canonical, Debian, Fedoraproject and 5 more 22 Ubuntu Linux, Debian Linux, Fedora and 19 more 2023-11-07 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
CVE-2019-6111 10 Apache, Canonical, Debian and 7 more 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more 2023-11-07 5.8 MEDIUM 5.9 MEDIUM
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) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2023-11-07 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2019-5798 6 Canonical, Debian, Google and 3 more 7 Ubuntu Linux, Debian Linux, Chrome and 4 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
Lack of correct bounds checking in Skia in Google Chrome prior to 73.0.3683.75 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
CVE-2019-5010 4 Debian, Opensuse, Python and 1 more 7 Debian Linux, Leap, Python and 4 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability.
CVE-2019-3880 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Leap and 3 more 2023-11-07 5.5 MEDIUM 5.4 MEDIUM
A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.
CVE-2019-3878 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 10 Ubuntu Linux, Fedora, Mod Auth Mellon and 7 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication.
CVE-2019-3877 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 4 Ubuntu Linux, Fedora, Mod Auth Mellon and 1 more 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function.
CVE-2019-3857 7 Debian, Fedoraproject, Libssh2 and 4 more 13 Debian Linux, Fedora, Libssh2 and 10 more 2023-11-07 6.8 MEDIUM 8.8 HIGH
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way SSH_MSG_CHANNEL_REQUEST packets with an exit signal are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3856 7 Debian, Fedoraproject, Libssh2 and 4 more 13 Debian Linux, Fedora, Libssh2 and 10 more 2023-11-07 6.8 MEDIUM 8.8 HIGH
An integer overflow flaw, which could lead to an out of bounds write, was discovered in libssh2 before 1.8.1 in the way keyboard prompt requests are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3855 8 Apple, Debian, Fedoraproject and 5 more 14 Xcode, Debian Linux, Fedora and 11 more 2023-11-07 9.3 HIGH 8.8 HIGH
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3842 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2023-11-07 4.4 MEDIUM 7.0 HIGH
In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any".
CVE-2019-3839 6 Artifex, Canonical, Debian and 3 more 6 Ghostscript, Ubuntu Linux, Debian Linux and 3 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.
CVE-2019-3838 5 Artifex, Debian, Fedoraproject and 2 more 12 Ghostscript, Debian Linux, Fedora and 9 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 16 Ubuntu Linux, Debian Linux, Libcurl and 13 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-3460 4 Canonical, Debian, Linux and 1 more 16 Ubuntu Linux, Debian Linux, Linux Kernel and 13 more 2023-11-07 3.3 LOW 6.5 MEDIUM
A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel before 5.1-rc1.
CVE-2019-3459 4 Canonical, Debian, Linux and 1 more 16 Ubuntu Linux, Debian Linux, Linux Kernel and 13 more 2023-11-07 3.3 LOW 6.5 MEDIUM
A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before 5.1-rc1.
