libcaca is affected by a Divide By Zero issue via img2txt, which allows a remote malicious user to cause a Denial of Service

A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.

A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be accessible.

A security issue was found in Linux kernel’s OverlayFS subsystem where a local attacker who has the ability to mount the TmpFS filesystem with OverlayFS can abuse a logic bug in the overlayfs code which can inadvertently reveal files hidden in the original mount.

saitoha libsixel v1.8.6 was discovered to contain a double free via the component sixel_chunk_destroy at /root/libsixel/src/chunk.c.

Null pointer dereference in the htmldoc v1.9.11 and before may allow attackers to execute arbitrary code and cause a denial of service via a crafted html file.

A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in render_table_row(),in ps-pdf.cxx may lead to arbitrary code execution and denial of service.

OS4ED openSIS 8.0 is affected by cross-site scripting (XSS) in EmailCheckOthers.php. An attacker can inject JavaScript code to get the user's cookie and take over the working session of user.
