NotEnough

Huffman表构建工具 此工具用于计算棘手的规范哈夫曼直方图，该直方图能够触发易受攻击的libwebp库（即 libwebp = 1.3.1）的越界（OOB）写入。此漏洞编号为 CVE-2023-4863 或 CVE-2023-41064。我们最多可以溢出预分配的哈夫曼表 132 个条目 。 原理在于，libwebp 假设每个 webp 图像中包含的哈夫曼直方图格式良好。也就是说，解码树必须是一棵完全树 。基于这一假设，libwebp 团队利用 enough 工具来估算构建解码哈夫曼表（一种用于快速解码规范哈夫曼码的强大结构）所需的最大内存大小。然而，攻击者能够构造一棵不完全树...

rsync: rsync: Information disclosure and denial of service via crafted files-from entry

A flaw was found in rsync. Remote unauthenticated attackers can exploit a heap out-of-bounds write vulnerability by supplying a crafted files-from entry. This entry, containing both an interior and trailing backslash, causes the addimpliedinclude function to under-count the trailing backslash whe...

Important: Red Hat Security Advisory: rsync security, bug fix, and enhancement update

An update for rsync is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the...

rsync: rsync: Arbitrary file write via path traversal in --relative mode

A path traversal vulnerability in rsync's --relative mode allows a malicious sender to craft symlink paths, enabling arbitrary file writes outside the destination directory...

rsync: rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink

A path traversal and symlink vulnerability in rsync allows a malicious sender with write access to write files outside the intended directory. By exploiting symbolic links in conjunction with the --partial-dir or --backup-dir options, an attacker can bypass path restrictions to modify arbitrary...

rsync: rsync: Heap Out-of-Bounds Write via crafted argument list

A flaw was found in rsync. A remote attacker could exploit an out-of-bounds write vulnerability in the readargs function by sending a specially crafted argument list. This could lead to corruption of adjacent memory, potentially causing a denial of service or, in some cases, arbitrary code...

rsync: rsync: Directory escape via TOCTOU race condition in rrsync

A time-of-check to time-of-use TOCTOU race condition flaw in the rrsync restricted shell wrapper allows authenticated remote attackers to escape directory restrictions. By replacing a validated path component with a symbolic link prior to file transfer execution, an attacker can bypass intended...

rsync: rsync: Arbitrary file write via --temp-dir or --link-dest options

A flaw was found in rsync. A remote attacker can exploit this vulnerability by specifying an absolute path using the --temp-dir or --link-dest options. This bypasses the rename-confinement logic, allowing the attacker to write files to arbitrary locations outside the intended destination tree,...

rsync: rsync: Memory corruption via crafted file entries

A flaw was found in rsync. This out-of-bounds write vulnerability allows attackers to corrupt memory by triggering specific processing on specially crafted file entries when hard-link preservation is not active. This can lead to denial of service or other unpredictable system behavior...

rsync: rsync < 3.5.0 Path Confinement Bypass via /./ Boundary Marker in Chroot Mode

A flaw was found in rsync. This vulnerability allows remote clients to bypass path confinement, a security measure designed to restrict file access. By crafting specific paths that include a '/./' boundary marker within a chroot environment, an attacker can gain unauthorized read or write access ...
