CVE-2018-7731 2 Canonical, Exempi Project 2 Ubuntu Linux, Exempi 2020-10-26 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FormatSupport/WEBP_Support.cpp does not check whether a bitstream has a NULL value, leading to a NULL pointer dereference in the WEBP::VP8XChunk class.
CVE-2018-7730 3 Canonical, Debian, Exempi Project 3 Ubuntu Linux, Debian Linux, Exempi 2020-10-26 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Exempi through 2.4.4. A certain case of a 0xffffffff length is mishandled in XMPFiles/source/FormatSupport/PSIR_FileWriter.cpp, leading to a heap-based buffer over-read in the PSD_MetaHandler::CacheFileData() function.
CVE-2018-7728 3 Canonical, Debian, Exempi Project 3 Ubuntu Linux, Debian Linux, Exempi 2020-10-26 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FileHandlers/TIFF_Handler.cpp mishandles a case of a zero length, leading to a heap-based buffer over-read in the MD5Update() function in third-party/zuid/interfaces/MD5.cpp.
CVE-2017-14174 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2020-10-23 7.1 HIGH 6.5 MEDIUM
In coders/psd.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "length" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.

Combined with another vulnerability, it can be used to leak stack memory layout and in bypassing ASLR
CVE-2018-20021 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 7.8 HIGH 7.5 HIGH
LibVNC before commit c3115350eb8bb635d0fdb4dbbb0d0541f38ed19c contains a CWE-835: Infinite loop vulnerability in VNC client code. Vulnerability allows attacker to consume excessive amount of resources like CPU and RAM
CVE-2018-20020 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 7b1ef0ffc4815cab9a96c7278394152bdc89dc4d contains heap out-of-bound write vulnerability inside structure in VNC client code that can result remote code execution
CVE-2018-15127 4 Canonical, Debian, Libvnc Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2020-10-23 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 502821828ed00b4a2c4bef90683d0fd88ce495de contains heap out-of-bound write vulnerability in server code of file transfer extension that can result remote code execution
CVE-2014-6054 3 Canonical, Debian, Libvncserver 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 4.3 MEDIUM N/A
The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier allows remote attackers to cause a denial of service (divide-by-zero error and server crash) via a zero value in the scaling factor in a (1) PalmVNCSetScaleFactor or (2) SetScale message.
CVE-2014-6053 3 Canonical, Debian, Libvncserver 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 5.0 MEDIUM N/A
The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a large amount of ClientCutText data, which allows remote attackers to cause a denial of service (memory consumption or daemon crash) via a crafted message that is processed by using a single unchecked malloc.
CVE-2014-6052 4 Canonical, Debian, Libvncserver and 1 more 4 Ubuntu Linux, Debian Linux, Libvncserver and 1 more 2020-10-23 7.5 HIGH N/A
The HandleRFBServerMessage function in libvncclient/rfbproto.c in LibVNCServer 0.9.9 and earlier does not check certain malloc return values, which allows remote VNC servers to cause a denial of service (application crash) or possibly execute arbitrary code by specifying a large screen size in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3) PalmVNCReSizeFrameBuffer message.
CVE-2018-7225 4 Canonical, Debian, Libvncserver Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2020-10-23 7.5 HIGH 9.8 CRITICAL
An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets.

CVE-2016-5105 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-10-21 1.9 LOW 4.4 MEDIUM
The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command.
