Astra Linux – Vulnerability in libpng1.6

LIBPNG is a reference library used in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. In versions 1.2.1 through 1.6.55, pngsettRNS and pngsetPLTE each act as aliases for a heap-allocated buffer between pngstruct and pnginfo. This buffer shares a...

nokogiri: Nokogiri: Denial of Service or Information Disclosure via invalid encoding handling

A flaw was found in Nokogiri, an XML and HTML library for Ruby. When an attacker provides an invalid encoding to the Documentencoding= function, the library frees the document's current encoding string without replacing it. This leaves the document referencing freed memory, which can lead to a...

libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

CVE-2026-63979

A flaw was found in the Linux kernel's net/handshake component. A race condition exists where a network handshake request can be removed and its associated file reference released concurrently while the accept-side code attempts to access it. This can lead to the system attempting to read from...

CVE-2026-63927

A flaw was found in the Linux kernel, specifically within the dwc2 USB driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released. This happens because a USB Request Block urb is incorrectly accessed after it has been...

The vulnerability of the mptcp_pm_del_add_timer() function in the net/mptcp/pm.c module of the MPTCP protocol implementation in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.
