An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process’s memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11

A use-after-free vulnerability exists in the _3MF_Importer::_handle_end_model() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted 3MF file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.

Within the function HandleFileArg the argument filepattern is under control of the user who passes it in from the command line. filepattern is passed directly to memcpy copying the path provided by the user into a staticly sized buffer without any length checks resulting in a stack-buffer overflow.

A stack-based buffer overflow vulnerability exists in the command-line-parsing HandleFileArg functionality of AT&T Labs’ Xmill 0.7. Within the function HandleFileArg the argument filepattern is under control of the user who passes it in from the command line. filepattern is passed directly to strcpy copying the path provided by the user into a static sized buffer without any length checks resulting in a stack-buffer overflow. An attacker can provide malicious input to trigger these vulnerabilities.

FFmpeg version (git commit de8e6e67e7523e48bb27ac224a0b446df05e1640) suffers from a an assertion failure at src/libavutil/mathematics.c.

A stack-based buffer overflow in the genpstrx_text() component in genpstricks.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pstricks format.

A stack-based buffer overflow in the genptk_text component in genptk.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ptk format.

A stack-based buffer overflow in the put_arrow() component in genpict2e.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pict2e format.

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An infinite loop was found in Exiv2 versions v0.27.4 and earlier. The infinite loop is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the image ICC profile, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p C`). The bug is fixed in version v0.27.5.

An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when deleting the IPTC data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-d I rm`). The bug is fixed in version v0.27.5.
