io.netty/netty-codec-xml: Netty: Information disclosure via XML External Entity (XXE) vulnerability

A flaw was found in Netty, a network application framework. A remote attacker could exploit this vulnerability by sending specially crafted XML data containing a DOCTYPE declaration to a vulnerable XmlDecoder within the Netty channel pipeline. This can lead to an XML External Entity XXE...

io.netty/netty-codec-stomp: Netty: Denial of Service vulnerability in STOMP decoder

A flaw was found in Netty, a network application framework, specifically within the StompSubframeDecoder component. This vulnerability allows a remote attacker to cause a denial of service DoS by sending a large number of small headers. The decoder fails to properly limit the total number or...

CVE-2026-70452 rsync 3.1.0 < 3.5.0 Access Control Bypass via DNS Resolution Failure

rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based deny rule fails, the daemon skips the ru...

CVE-2026-70452

rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability: DNS-resolution failures during hostname-based deny rule evaluation cause the daemon to skip the rule instead of denying, enabling unauthorized access to restricted module file trees by attackers who can trigger DNS failures...

CVE-2026-70453 rsync < 3.5.0 Algorithmic Complexity DoS via hash_search()

rsync before 3.5.0 contains an algorithmic complexity vulnerability in the hashsearch function that allows a remote attacker to cause a denial of service by delivering a carefully constructed file list. A sender can exploit the quadratic-time worst-case behavior in hash lookups to exhaust receive...

CVE-2026-70455 rsync 3.4.2 < 3.5.0 DoS via --zt Zstandard Compression Thread Exhaustion

rsync 3.4.2 before 3.5.0 contains a denial of service vulnerability that allows a remote sender to exhaust system resources by specifying the --zt short alias for --compress-threads, which bypasses the refuse options directive's string matching on long option names. Attackers can specify --zt=N...

CVE-2026-70459 rsync 3.0.0 < 3.5.0 Daemon Crash via Malformed File List Entry

rsync 3.0.0 before 3.5.0 contains a null pointer dereference vulnerability in the daemon child process that allows remote attackers to crash the daemon by sending a file list whose first entry is a dot entry not typed as a directory. The daemon dereferences the first file list entry as a director...

CVE-2026-70459

rsync 3.0.0 before 3.5.0 is affected by a null pointer dereference in the daemon child process when processing a file list whose first entry is a dot entry not typed as a directory. The daemon dereferences the entry as a directory structure pointer without type verification, causing an invalid/un...

CVE-2026-70461

CVE-2026-70461 affects rsync 3.2.5 before 3.5.0. A heap out-of-bounds write is possible when processing a crafted files-from entry, allowing remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation. The issue is triggered when a files-from entry con...

CVE-2026-70461

rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsyn...
