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-2026-43619

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...

DEBIAN-CVE-2026-43620

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...

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...
