CVE-2019-16056 | 7 Canonical, Debian, Fedoraproject and 4 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally. | |||||
CVE-2019-15961 | 4 Canonical, Cisco, Clamav and 1 more | 4 Ubuntu Linux, Email Security Appliance Firmware, Clamav and 1 more | 2024-11-21 | 7.1 HIGH | 7.5 HIGH |
A vulnerability in the email parsing module Clam AntiVirus (ClamAV) Software versions 0.102.0, 0.101.4 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to inefficient MIME parsing routines that result in extremely long scan times of specially formatted email files. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to scan the crafted email file indefinitely, resulting in a denial of service condition. | |||||

CVE-2019-15845 | 2 Canonical, Ruby-lang | 2 Ubuntu Linux, Ruby | 2024-11-21 | 6.4 MEDIUM | 6.5 MEDIUM |
Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions. | |||||
CVE-2019-15796 | 3 Canonical, Debian, Ubuntu | 3 Ubuntu Linux, Python-apt, Python-apt | 2024-11-21 | 2.6 LOW | 4.7 MEDIUM |
Python-apt doesn't check if hashes are signed in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py or in `_fetch_archives()` of apt/cache.py in version 1.9.3ubuntu2 and earlier. This allows downloads from unsigned repositories which shouldn't be allowed and has been fixed in verisions 1.9.5, 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5. | |||||
CVE-2019-15795 | 3 Canonical, Debian, Ubuntu | 3 Ubuntu Linux, Python-apt, Python-apt | 2024-11-21 | 2.6 LOW | 4.7 MEDIUM |
python-apt only checks the MD5 sums of downloaded files in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py in version 1.9.0ubuntu1 and earlier. This allows a man-in-the-middle attack which could potentially be used to install altered packages and has been fixed in versions 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5. | |||||
CVE-2019-15794 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.2 HIGH | 7.1 HIGH |
Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow. | |||||
CVE-2019-15793 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 4.6 MEDIUM | 6.5 MEDIUM |
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into init_user_ns, whereas they should have been translated into the s_user_ns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts s_user_ns. A local attacker could use this to possibly bypass discretionary access control permissions. | |||||
CVE-2019-15792 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 4.6 MEDIUM | 7.1 HIGH |
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() calls fdget(oldfd), then without further checks passes the resulting file* into shiftfs_real_fdget(), which casts file->private_data, a void* that points to a filesystem-dependent type, to a "struct shiftfs_file_info *". As the private_data is not required to be a pointer, an attacker can use this to cause a denial of service or possibly execute arbitrary code. | |||||
CVE-2019-15791 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 4.6 MEDIUM | 7.1 HIGH |
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow. | |||||
CVE-2019-15790 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2024-11-21 | 2.1 LOW | 2.8 LOW |
Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through get_pid_info() in data/apport. An unprivileged user could exploit this to read information about a privileged running process by exploiting PID recycling. This information could then be used to obtain ASLR offsets for a process with an existing memory corruption vulnerability. The initial fix introduced regressions in the Python Apport library due to a missing argument in Report.add_proc_environ in apport/report.py. It also caused an autopkgtest failure when reading /proc/pid and with Python 2 compatibility by reading /proc maps. The initial and subsequent regression fixes are in 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 and 2.14.1-0ubuntu3.29+esm3. | |||||
CVE-2019-15789 | 1 Canonical | 1 Microk8s | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
Privilege escalation vulnerability in MicroK8s allows a low privilege user with local access to obtain root access to the host by provisioning a privileged container. Fixed in MicroK8s 1.15.3. | |||||
CVE-2019-15717 | 2 Canonical, Irssi | 2 Ubuntu Linux, Irssi | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |

CVE-2019-15681 | 4 Canonical, Debian, Libvnc Project and 1 more | 15 Ubuntu Linux, Debian Linux, Libvncserver and 12 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
LibVNC commit before d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a contains a memory leak (CWE-655) in VNC server code, which allow an attacker to read stack memory and can be abused for information disclosure. Combined with another vulnerability, it can be used to leak stack memory and bypass ASLR. This attack appear to be exploitable via network connectivity. These vulnerabilities have been fixed in commit d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a. | |||||

CVE-2019-15538 | 6 Canonical, Debian, Fedoraproject and 3 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS. | |||||
