CVE-2019-19055 3 Canonical, Fedoraproject, Linux 3 Ubuntu Linux, Fedora, Linux Kernel 2020-08-24 4.9 MEDIUM 5.5 MEDIUM
** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred.
CVE-2019-19047 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-08-24 4.9 MEDIUM 5.5 MEDIUM
A memory leak in the mlx5_fw_fatal_reporter_dump() function in drivers/net/ethernet/mellanox/mlx5/core/health.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mlx5_crdump_collect() failures, aka CID-c7ed6d0183d5.
CVE-2019-12749 2 Canonical, Freedesktop 2 Ubuntu Linux, Dbus 2020-08-24 3.6 LOW 7.1 HIGH
dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass.
CVE-2019-6251 6 Canonical, Fedoraproject, Gnome and 3 more 6 Ubuntu Linux, Fedora, Epiphany and 3 more 2020-08-24 5.8 MEDIUM 8.1 HIGH
WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge.
CVE-2019-19072 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2020-08-24 4.9 MEDIUM 4.4 MEDIUM
A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.
CVE-2019-16275 3 Canonical, Debian, W1.fi 4 Ubuntu Linux, Debian Linux, Hostapd and 1 more 2020-08-24 3.3 LOW 6.5 MEDIUM
hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range.
CVE-2019-6215 3 Apple, Canonical, Microsoft 8 Icloud, Iphone Os, Itunes and 5 more 2020-08-24 6.8 MEDIUM 8.8 HIGH
A type confusion issue was addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2019-18197 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2020-08-24 5.1 MEDIUM 7.5 HIGH
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
CVE-2019-12447 4 Canonical, Fedoraproject, Gnome and 1 more 4 Ubuntu Linux, Fedora, Gvfs and 1 more 2020-08-24 4.9 MEDIUM 7.3 HIGH
An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used.
CVE-2019-17025 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 71. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 72.
CVE-2019-12449 4 Canonical, Fedoraproject, Gnome and 1 more 4 Ubuntu Linux, Fedora, Gvfs and 1 more 2020-08-24 3.5 LOW 5.7 MEDIUM
An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a file's user and group ownership during move (and copy with G_FILE_COPY_ALL_METADATA) operations from admin:// to file:// URIs, because root privileges are unavailable.
CVE-2019-6133 4 Canonical, Debian, Polkit Project and 1 more 9 Ubuntu Linux, Debian Linux, Polkit and 6 more 2020-08-24 4.4 MEDIUM 6.7 MEDIUM
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
CVE-2019-19602 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-08-24 5.4 MEDIUM 6.1 MEDIUM
fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.
CVE-2019-15030 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2020-08-24 3.6 LOW 4.4 MEDIUM
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check.
CVE-2019-0154 2 Canonical, Intel 295 Ubuntu Linux, Atom X5-a3930, Atom X5-a3930 Firmware and 292 more 2020-08-24 2.1 LOW 5.5 MEDIUM
Insufficient access control in subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100 Processor Families may allow an authenticated user to potentially enable denial of service via local access.
CVE-2018-6913 3 Canonical, Debian, Perl 3 Ubuntu Linux, Debian Linux, Perl 2020-08-24 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.
CVE-2019-6212 3 Apple, Canonical, Microsoft 7 Icloud, Iphone Os, Itunes and 4 more 2020-08-24 6.8 MEDIUM 8.8 HIGH
Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2019-11068 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxslt 2020-08-24 7.5 HIGH 9.8 CRITICAL
libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.
CVE-2018-6797 4 Canonical, Debian, Perl and 1 more 5 Ubuntu Linux, Debian Linux, Perl and 2 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.
CVE-2018-5810 2 Canonical, Libraw 2 Ubuntu Linux, Libraw 2020-08-24 6.8 MEDIUM 8.8 HIGH
An error within the "rollei_load_raw()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.9 can be exploited to cause a heap-based buffer overflow and subsequently cause a crash.
