A flaw was found in PolicyKit (aka polkit) 0.115 that allows a user with a uid greater than INT_MAX to successfully execute any systemctl command.
CVE-2018-19149 2 Canonical, Freedesktop 2 Ubuntu Linux, Poppler 2019-08-06 4.3 MEDIUM 6.5 MEDIUM
Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from poppler_annot_file_attachment_get_attachment.
CVE-2018-19060 2 Canonical, Freedesktop 2 Ubuntu Linux, Poppler 2019-08-06 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Poppler 0.71.0. There is a NULL pointer dereference in goo/GooString.h, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating a filename of an embedded file before constructing a save path.
CVE-2018-19059 2 Canonical, Freedesktop 2 Ubuntu Linux, Poppler 2019-08-06 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Poppler 0.71.0. There is a out-of-bounds read in EmbFile::save2 in FileSpec.cc, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating embedded files before save attempts.
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.
CVE-2018-17336 2 Canonical, Freedesktop 2 Ubuntu Linux, Udisks 2019-08-06 4.6 MEDIUM 7.8 HIGH
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.
