check_icmp_dos-CVE-2018-4407-

Principio El principio consiste en hacer que otros campos del paquete "icmp" sean inválidos; cuando el kernel de macOS o iPhone los analiza, no se ha implementado la comprobación de tamaño, lo que provoca un crash. Dispositivos 1. Apple iOS 11 y versiones anteriores: todos los dispositivos 2. App...

Bypass-Sandbox-Evasion

Bypass-Sandbox-Evasion Sandboxes are commonly used to analyze malware. They provide a temporary, isolated, and secure environment in which to observe whether a suspicious file exhibits any malicious behavior. However, malware developers have also developed methods to evade sandboxes and analysis...

OESA-2026-3815 pcre2 security update

PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: transportipc: Validate the payload size before reading the handle. The handleresponse function dereferences the payload as a 4-byte handle without verifying that the declared payload size is at least 4 bytes. A malformed o...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Fixed a slab out-of-bounds write in smbinheritdacl. The slab out-of-bounds write occurs because the offsets are larger than the allocation size of pntsd. This patch adds a check to validate the three offsets using the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Validating UAC3 cluster segment descriptors UAC3 class segment descriptors need to be verified to ensure that their sizes match the declared lengths, and that they fit within the allocated buffer sizes as well...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nilfs2: A shift-out-of-bounds condition has been fixed due to an overly large exponent of the block size. If the slogblocksize field in the superblock data is corrupted and too large, initnilfs and loadnilfs may still trigger a...

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Added a rough attrallocsize check...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Added a size check of 0 bytes to mtkdrmgemobj. A check was added to mtkdrmgeminit if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists, and the kernel will panic if a user-space...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the Big Requests extension. The length of the request is multiplied by 4 before checking against the maximum allowed size, which may lead to an integer overflow and bypassing the size check...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The validation of the request buffer size was added in smb2allocaterspbuf. The response buffer should be allocated in smb2allocaterspbuf before validation of the request. However, fields within the payload as well as the...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: gfs2: Always check the inode size of inline inodes. Check whether the inode size of inline inodes is within the allowed range when reading inodes from the disk gfs2dinodein. This prevents on-disk corruption. The two checks in...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Platform/x86: panasonic-laptop: Fixed out-of-bounds accesses to the SINF array. The panasonic laptop code in various places uses the SINF array with index values ranging from 0 to SINFCURBRIGHT0x0d, without checking whether the...
