When generating the systemd service units for the docker snap (and other similar snaps), snapd does not specify Delegate=yes - as a result systemd will move processes from the containers created and managed by these snaps into the cgroup of the main daemon within the snap itself when reloading system units. This may grant additional privileges to a container within the snap that were not originally intended.

Accountsservice incorrectly drops privileges

accountsservice no longer drops permissions when writting .pam_environment

gnome-control-center: Remote login misconfiguration in GNOME Control Center

In Ubuntu, gnome-control-center did not properly reflect SSH remote login status when the system was configured to use systemd socket activation for openssh-server. This could unknowingly leave the local machine exposed to remote SSH access contrary to expectation of the user.

unzip: free() called for uninitialized or already freed pointer

The NEEDBITS macro in the inflate_dynamic function in inflate.c for unzip can be invoked using invalid buffers, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors that trigger a free of uninitialized or previously-freed data.

Apport can be tricked into connecting to arbitrary sockets as the root user

audiofile: Buffer overflow when changing number of channels and sample format

Buffer overflow in the afReadFrames function in audiofile (aka libaudiofile and Audio File Library) allows user-assisted remote attackers to cause a denial of service (program crash) or possibly execute arbitrary code via a crafted audio file, as demonstrated by sixteen-stereo-to-eight-mono.c.

audiofile: Heap-based buffer overflow in Expand3To4Module::run() when running sfconvert

An issue has been discovered in mpruett Audio File Library (aka audiofile) 0.3.6, 0.3.5, 0.3.4, 0.3.3, 0.3.2, 0.3.1, 0.3.0. A heap-based buffer overflow in Expand3To4Module::run has occurred when running sfconvert.

audiofile: NULL pointer dereference in ModuleState::setup() in modules/ModuleState.cpp allows for denial of service via crafted file

The audiofile Audio File Library 0.3.6 has a NULL pointer dereference bug in ModuleState::setup in modules/ModuleState.cpp, which allows an attacker to cause a denial of service via a crafted caf file, as demonstrated by sfconvert.

MileSight DeviceHub - CWE-320: Key Management Errors may allow Authentication Bypass and Man-In-The-Middle Traffic

ImageMagick: division by zero in RemoveDuplicateLayers in MagickCore/layer.c

ImageMagick 7.0.1-0 to 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.

zziplib: out of bound read in mmapped.c:zzip_disk_fread() causes crash

An issue was discovered in ZZIPlib 0.13.68. An invalid memory address dereference was discovered in zzip_disk_fread in mmapped.c. The vulnerability causes an application crash, which leads to denial of service.

zziplib: Bus error in zip.c:__zzip_parse_root_directory() cause crash via crafted zip file

An issue was discovered in ZZIPlib 0.13.68. There is a bus error caused by the __zzip_parse_root_directory function of zip.c. Attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

zziplib: bus error in zzip_disk_findfirst function in zzip/mmapped.c

In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

zziplib: Loading of misaligned memory address in zip.c:__zzip_fetch_disk_trailer can lead to a denial of service via crafted zip file

In ZZIPlib 0.13.67, there is a memory alignment error and bus error in the __zzip_fetch_disk_trailer function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

zziplib: Bus error caused by loading of a misaligned address inzzip/zip.c

In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address (when handling disk64_trailer local entries) in __zzip_fetch_disk_trailer (zzip/zip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

zziplib: Invalid memory access in the zzip_disk_fread function in zzip/mmapped.c

In ZZIPlib 0.13.67, 0.13.66, 0.13.65, 0.13.64, 0.13.63, 0.13.62, 0.13.61, 0.13.60, 0.13.59, 0.13.58, 0.13.57 and 0.13.56 there is a segmentation fault caused by invalid memory access in the zzip_disk_fread function (zzip/mmapped.c) because the size variable is not validated against the amount of file->stored data.

zziplib: uncontrolled memory allocation in __zzip_parse_root_directory in zzip/zip.c

In ZZIPlib 0.13.68, there is an uncontrolled memory allocation and a crash in the __zzip_parse_root_directory function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

busybox: Out of bounds read in udhcp components resulting in information disclosure

An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679.

systemd: memory leak in button_open() in login/logind-button.c when udev events are received

An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.

systemd: Mishandled symlinks in systemd-tmpfiles allows local users to obtain ownership of arbitrary files

systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.
