Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the...

CVE-2026-59901 Netty Bzip2Decoder: Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the...

CVE-2026-59901

Netty CVE-2026-59901 affects the Bzip2Decoder in the compression codec pipeline. The issue is a flaw in the Bzip2BlockDecompressor.read() RLE state machine that can cause an infinite loop, hanging the event-loop thread and triggering DoS. Fixed in Netty versions 4.1.136.Final and 4.2.16.Final. Af...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

CVE-2026-67191

Xlight FTP Server before 3.9.5 contains a pre-authentication heap buffer overflow vulnerability that allows remote unauthenticated attackers to write past the end of a heap buffer by sending a malformed SSH client identification string. A logic error in the recv loop's termination condition uses ...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the customRandom function in the customRandom implementation. An attacker can hang the calling thread by supplying a size of 0 to customRandom, which causes its ID generation loop to never reach a terminating...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the customAlphabet and nanoid functions in nanoid/non-secure. An attacker can hang the calling thread by supplying a negative size to either function, causing the loop counter to decrement from a negative value and...

CVE-2026-67191 Xlight FTP Server < 3.9.5 Pre-Auth Heap Buffer Overflow via SSH Parser

Xlight FTP Server before 3.9.5 contains a pre-authentication heap buffer overflow vulnerability that allows remote unauthenticated attackers to write past the end of a heap buffer by sending a malformed SSH client identification string. A logic error in the recv loop's termination condition uses ...

CVE-2026-67191

Xlight FTP Server prior to 3.9.5 is affected by a pre-authentication heap buffer overflow in the SSH parser. A logic error in the recv loop termination (OR instead of AND) enables exploitation on any SSH or SFTP connection before authentication, allowing remote unauthenticated access with high im...

GHSA-2V37-7H3G-55P8 nanoid: custom generators can loop indefinitely when size is zero

nanoid Nano ID before 5.1.6 contains an infinite loop in the customAlphabet and customRandom functions. When these functions are configured with a size of 0, the internal generation loop never satisfies its exit condition and spins indefinitely, hanging the calling thread. An application that...

GHSA-28WG-GHJ8-5HJV nanoid: non-secure generators can loop indefinitely with negative size

nanoid Nano ID before 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module nanoid/non-secure. When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, spinning...
