CVE-2018-18661 2 Canonical, Libtiff 2 Ubuntu Linux, Libtiff 2019-08-06 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in LibTIFF 4.0.9. There is a NULL pointer dereference in the function LZWDecode in the file tif_lzw.c.

UDisks 2.8.0 has a format string vulnerability in udisks_log in udiskslogging.c, allowing attackers to obtain sensitive information (stack contents), cause a denial of service (memory corruption), or possibly have unspecified other impact via a malformed filesystem label, as demonstrated by %d or %n substrings.
CVE-2018-16842 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2019-08-06 6.4 MEDIUM 9.1 CRITICAL
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.
CVE-2018-16658 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-08-06 3.6 LOW 6.1 MEDIUM
An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940.
CVE-2018-15855 2 Canonical, Xkbcommon Project 2 Ubuntu Linux, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because the XkbFile for an xkb_geometry section was mishandled.
CVE-2018-15854 2 Canonical, Xkbcommon Project 2 Ubuntu Linux, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because geometry tokens were desupported incorrectly.
CVE-2018-15853 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean negation.
CVE-2018-15864 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in resolve_keysym in xkbcomp/parser.y in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because a map access attempt can occur for a map that was never created.
CVE-2018-15863 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in ResolveStateAndPredicate in xkbcomp/compat.c in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file with a no-op modmask expression.
CVE-2018-15862 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in LookupModMask in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file with invalid virtual modifiers.
CVE-2018-15861 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in ExprResolveLhs in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file that triggers an xkb_intern_atom failure.
CVE-2018-15859 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage when parsing invalid atoms in ExprResolveLhs in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because lookup failures are mishandled.
CVE-2018-15857 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2019-08-06 4.6 MEDIUM 7.8 HIGH
An invalid free in ExprAppendMultiKeysymList in xkbcomp/ast-build.c in xkbcommon before 0.8.1 could be used by local attackers to crash xkbcommon keymap parsers or possibly have unspecified other impact by supplying a crafted keymap file.
CVE-2018-14600 3 Canonical, Debian, X.org 3 Ubuntu Linux, Debian Linux, Libx11 2019-08-06 7.5 HIGH 9.8 CRITICAL
An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution.
CVE-2018-14598 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2019-08-06 5.0 MEDIUM 7.5 HIGH
An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault).
CVE-2018-12265 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2019-08-06 6.8 MEDIUM 8.8 HIGH
Exiv2 0.26 has an integer overflow in the LoaderExifJpeg class in preview.cpp, leading to an out-of-bounds read in Exiv2::MemIo::read in basicio.cpp.
CVE-2018-12264 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2019-08-06 6.8 MEDIUM 8.8 HIGH
Exiv2 0.26 has integer overflows in LoaderTiff::getData() in preview.cpp, leading to an out-of-bounds read in Exiv2::ValueType::setDataArea in value.hpp.
CVE-2018-10958 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2019-08-06 4.3 MEDIUM 6.5 MEDIUM
In types.cpp in Exiv2 0.26, a large size value may lead to a SIGABRT during an attempt at memory allocation for an Exiv2::Internal::PngChunk::zlibUncompress call.
CVE-2017-18234 3 Canonical, Debian, Exempi Project 3 Ubuntu Linux, Debian Linux, Exempi 2019-08-06 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Exempi before 2.4.3. It allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data, related to XMPFiles/source/FormatSupport/ReconcileTIFF.cpp, XMPFiles/source/FormatSupport/TIFF_MemoryReader.cpp, and XMPFiles/source/FormatSupport/TIFF_Support.hpp.
CVE-2016-3616 4 Canonical, Debian, Libjpeg-turbo and 1 more 4 Ubuntu Linux, Debian Linux, Libjpeg-turbo and 1 more 2019-08-06 6.8 MEDIUM 8.8 HIGH
The cjpeg utility in libjpeg allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or execute arbitrary code via a crafted file.
