A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.

Workaround There's no known mitigation available for this vulnerability.

A heap based buffer overflow flaw has been discovered in LibPNG. Prior to version 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification.

A flaw was found in Vim, an open source, command line text editor. This heap buffer overflow vulnerability exists in the tag file resolution logic when processing the 'helpfile' option. A local user could exploit this by providing a specially crafted 'helpfile' option value, leading to a heap buffer overflow. This could result in arbitrary code execution or a denial of service.

A flaw was found in Vim, an open-source command-line text editor. Specifically, an operating system (OS) command injection vulnerability exists in the `netrw` standard plugin. A remote attacker could exploit this by tricking a user into opening a specially crafted URL, such as one using the `scp://` protocol handler. Successful exploitation allows the attacker to execute arbitrary shell commands with the same privileges as the Vim process, leading to potential system compromise.

A flaw was found in Vim. This vulnerability, a heap-buffer-overflow and a segmentation fault, exists in the swap file recovery logic. A local attacker could exploit this by providing a specially crafted swap file. This could lead to a denial of service (DoS) or potentially information disclosure.

A flaw was found in Vim. By including a newline character in a pattern passed to Vim's glob() function, an attacker may be able to execute arbitrary shell commands. This command injection vulnerability allows for arbitrary code execution, depending on the user's shell settings.
