Kernel: KVM: OOB memory access via mmio ring buffer

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.

dpdk: possible memory leak leads to denial of service

A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition.

ghostscript: Safer mode bypass by .forceput exposure in .pdfexectoken and other procedures (701450)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdfexectoken and other procedures where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443)

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in setuserparams (701444)

A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in .pdf_hook_DSC_Creator (701445)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

In radare2 before 3.7.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to improper handling of symbol names embedded in executables.

kdelibs: malicious desktop files and configuration files lead to code execution with minimal user interaction

In KDE Frameworks KConfig before 5.61.0, malicious desktop files and configuration files lead to code execution with minimal user interaction. This relates to libKF5ConfigCore.so, and the mishandling of .desktop and .directory files, as demonstrated by a shell command on an Icon line in a .desktop file.

In Enigmail below 2.1, an attacker in possession of PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, he unknowingly leaks the plaintext of the encrypted message part(s) back to the attacker. This attack variant bypasses protection mechanisms implemented after the "EFAIL" attacks.

An issue was discovered in The Sleuth Kit (TSK) 4.6.6. There is an off-by-one overwrite due to an underflow on tools/hashtools/hfind.cpp while using a bogus hash table.

poppler: divide-by-zero in function SplashOutputDev::tilingPatternFill in SplashOutputDev.cc

An issue was discovered in Poppler through 0.78.0. There is a divide-by-zero error in the function SplashOutputDev::tilingPatternFill at SplashOutputDev.cc.

XMFile::read in XMFile.cpp in milkyplay in MilkyTracker 1.02.00 has a heap-based buffer overflow.

An issue was discovered in libmodbus before 3.0.7 and 3.1.x before 3.1.5. There is an out-of-bounds read for the MODBUS_FC_WRITE_MULTIPLE_REGISTERS case, aka VD-1301.
