CVE-2015-6031 4 Canonical, Debian, Miniupnp Project and 1 more 5 Ubuntu Linux, Debian Linux, Miniupnpc and 2 more 2019-06-18 6.8 MEDIUM N/A
Buffer overflow in the IGDstartelt function in igd_desc_parse.c in the MiniUPnP client (aka MiniUPnPc) before 1.9.20150917 allows remote UPNP servers to cause a denial of service (application crash) and possibly execute arbitrary code via an "oversized" XML element name.
CVE-2019-9213 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2019-06-17 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.
CVE-2015-1781 4 Canonical, Debian, Gnu and 1 more 6 Ubuntu Linux, Debian Linux, Glibc and 3 more 2019-06-17 6.8 MEDIUM N/A
Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer.
CVE-2019-9917 3 Canonical, Fedoraproject, Znc 3 Ubuntu Linux, Fedora, Znc 2019-06-15 4.0 MEDIUM 6.5 MEDIUM
ZNC before 1.7.3-rc1 allows an existing remote user to cause a Denial of Service (crash) via invalid encoding.

It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users.
CVE-2019-7524 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2019-06-14 7.2 HIGH 7.8 HIGH
In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components.
CVE-2015-1472 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2019-06-13 7.5 HIGH N/A
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
CVE-2014-9402 3 Canonical, Gnu, Opensuse 3 Ubuntu Linux, Glibc, Opensuse 2019-06-13 7.8 HIGH N/A
The nss_dns implementation of getnetbyname in GNU C Library (aka glibc) before 2.21, when the DNS backend in the Name Service Switch configuration is enabled, allows remote attackers to cause a denial of service (infinite loop) by sending a positive answer while a network name is being process.
CVE-2014-9761 5 Canonical, Fedoraproject, Gnu and 2 more 9 Ubuntu Linux, Fedora, Glibc and 6 more 2019-06-13 7.5 HIGH 9.8 CRITICAL
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function.
CVE-2015-3196 7 Canonical, Debian, Fedoraproject and 4 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2019-06-13 4.3 MEDIUM N/A
ssl/s3_clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service (race condition and double free) via a crafted ServerKeyExchange message.
CVE-2015-2582 4 Canonical, Debian, Oracle and 1 more 10 Ubuntu Linux, Debian Linux, Mysql and 7 more 2019-06-13 4.0 MEDIUM N/A
Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote authenticated users to affect availability via vectors related to GIS.
CVE-2016-10714 2 Canonical, Zsh 2 Ubuntu Linux, Zsh 2019-06-11 7.5 HIGH 9.8 CRITICAL
In zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support PATH_MAX characters.
CVE-2014-10071 2 Canonical, Zsh 2 Ubuntu Linux, Zsh 2019-06-11 7.5 HIGH 9.8 CRITICAL
In exec.c in zsh before 5.0.7, there is a buffer overflow for very long fds in the ">& fd" syntax.
CVE-2018-11469 2 Canonical, Haproxy 2 Ubuntu Linux, Haproxy 2019-06-11 4.3 MEDIUM 5.9 MEDIUM

CVE-2019-9637 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-03 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.
CVE-2019-9675 3 Canonical, Opensuse, Php 3 Ubuntu Linux, Leap, Php 2019-06-03 6.8 MEDIUM 8.1 HIGH
** DISPUTED ** An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible."
CVE-2018-1000135 2 Canonical, Gnome 2 Ubuntu Linux, Networkmanager 2019-06-03 5.0 MEDIUM 7.5 HIGH
GNOME NetworkManager version 1.10.2 and earlier contains a Information Exposure (CWE-200) vulnerability in DNS resolver that can result in Private DNS queries leaked to local network's DNS servers, while on VPN. This vulnerability appears to have been fixed in Some Ubuntu 16.04 packages were fixed, but later updates removed the fix. cf. https://bugs.launchpad.net/ubuntu/+bug/1754671 an upstream fix does not appear to be available at this time.

CVE-2018-6556 4 Canonical, Linuxcontainers, Opensuse and 1 more 6 Ubuntu Linux, Lxc, Leap and 3 more 2019-05-31 2.1 LOW 3.3 LOW
lxc-user-nic when asked to delete a network interface will unconditionally open a user provided path. This code path may be used by an unprivileged user to check for the existence of a path which they wouldn't otherwise be able to reach. It may also be used to trigger side effects by causing a (read-only) open of special kernel files (ptmx, proc, sys). Affected releases are LXC: 2.0 versions above and including 2.0.9; 3.0 versions above and including 3.0.0, prior to 3.0.2.
CVE-2018-18954 3 Canonical, Opensuse, Qemu 3 Ubuntu Linux, Leap, Qemu 2019-05-31 2.1 LOW 5.5 MEDIUM

CVE-2019-3812 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2019-05-31 2.1 LOW 5.5 MEDIUM
QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.
CVE-2019-3885 3 Canonical, Clusterlabs, Fedoraproject 3 Ubuntu Linux, Pacemaker, Fedora 2019-05-27 5.0 MEDIUM 7.5 HIGH

CVE-2016-10712 2 Canonical, Php 2 Ubuntu Linux, Php 2019-05-22 5.0 MEDIUM 7.5 HIGH
In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker.

CVE-2018-5814 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-05-20 6.9 MEDIUM 7.0 HIGH
In the Linux Kernel before version 4.16.11, 4.14.43, 4.9.102, and 4.4.133, multiple race condition errors when handling probe, disconnect, and rebind operations can be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets.
CVE-2018-16880 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2019-05-16 6.9 MEDIUM 7.0 HIGH
A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
