CVE-2026-29518 Rsync < 3.4.3 TOCTOU Race Condition Allows Symlink-Based Arbitrary File Write
Rsync versions before 3.4.3 contain a time-of-check to time-of-use TOCTOU race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path ca...
USN-8283-1: rsync vulnerabilities
Calum Hutton discovered that rsync contained a heap-based out-of-bounds read when handling file transfers. A remote attacker with read access to an rsync server could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.1...

Integer Overflow or Wraparound
Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the compressed-token decoder process. An attacker can access sensitive memory contents, including environment variables, passwords, heap and stack data, and library memory pointers, by sending speciall...
Time-of-check Time-of-use (TOCTOU) Race Condition
Overview Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition via the timing window between path resolution and syscall execution in operations such as chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat. An attacker...
Off-by-one Error
Overview Affected versions of this package are vulnerable to Off-by-one Error via the establishproxyconnection function. An attacker can corrupt stack memory by sending a specially crafted HTTP proxy response line of 1023 or more bytes without a newline terminator, potentially leading to...
CVE-2026-43618
Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended...
CVE-2026-43619
Rsync version 3.4.2 and prior contain symlink race condition vulnerabilities in path-based system calls including chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat that allow local attackers to redirect operations to files outside the exported rsync module...
ALPINE-CVE-2026-43617
Rsync version 3.4.2 and prior contain an authorization bypass vulnerability in the rsync daemon's hostname-based access control list enforcement when configured with chroot. Attackers can bypass hostname-based deny rules by controlling the PTR record for their source IP address, allowing...
AZL-86991 CVE-2026-43620 affecting package rsync for versions less than 3.4.3-1
Rsync version 3.4.2 and prior contain a receiver-side out-of-bounds array read vulnerability in recvfiles in receiver.c that allows a malicious rsync server to crash the rsync client process. Attackers can exploit the vulnerability by setting CFINCRECURSE in compatibility flags and sending a...
