Alpine: multiple dnsdist packages: security update to 1.9.11-r0
high Tenable Cloud Security Plugin ID 435449
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Impact Cloudflare quiche was discovered to be vulnerable to incorrect congestion window growth, which
could cause it to send data at a rate faster than the path might actually support. An unauthenticated
remote attacker can exploit the vulnerability by first completing a handshake and initiating a congestion-
controlled data transfer towards itself. Then, it could manipulate the victim's congestion control state
by sending ACK frames exercising an opportunistic ACK attack; see RFC 9000 Section 21.4. The victim could
grow the congestion window beyond typical expectations and allow more bytes in flight than the path might
really support. Patches quiche 0.24.4 is the earliest version containing the fix for this issue.
(CVE-2025-4820)
- Impact Cloudflare quiche was discovered to be vulnerable to incorrect congestion window growth, which
could cause it to send data at a rate faster than the path might actually support. An unauthenticated
remote attacker can exploit the vulnerability by first completing a handshake and initiating a congestion-
controlled data transfer towards itself. Then, it could manipulate the victim's congestion control state
by sending ACK frames covering a large range of packet numbers (including packet numbers that had never
been sent); see RFC 9000 Section 19.3. The victim could grow the congestion window beyond typical
expectations and allow more bytes in flight than the path might really support. In extreme cases, the
window might grow beyond the limit of the internal variable's type, leading to an overflow panic. Patches
quiche 0.24.4 is the earliest version containing the fix for this issue. (CVE-2025-4821)
- Cloudflare quiche was discovered to be vulnerable to an infinite loop when sending packets containing
RETIRE_CONNECTION_ID frames. QUIC connections possess a set of connection identifiers (IDs); see Section
5.1 of RFC 9000 https://datatracker.ietf.org/doc/html/rfc9000#section-5.1 . Once the QUIC handshake
completes, a local endpoint is responsible for issuing and retiring Connection IDs that are used by the
remote peer to populate the Destination Connection ID field in packets sent from remote to local. Each
Connection ID has a sequence number to ensure synchronization between peers. An unauthenticated remote
attacker can exploit this vulnerability by first completing a handshake and then sending a specially-
crafted set of frames that trigger a connection ID retirement in the victim. When the victim attempts to
send a packet containing RETIRE_CONNECTION_ID frames, Section 19.16 of RFC 9000
https://datatracker.ietf.org/doc/html/rfc9000#section-19.6 requires that the sequence number of the
retired connection ID must not be the same as the sequence number of the connection ID used by the packet.
In other words, a packet cannot contain a frame that retires itself. In scenarios such as path migration,
it is possible for there to be multiple active paths with different active connection IDs that could be
used to retire each other. The exploit triggered an unintentional behaviour of a quiche design feature
that supports retirement across paths while maintaining full connection ID synchronization, leading to an
infinite loop.This issue affects quiche: from 0.15.0 before 0.24.5. (CVE-2025-7054)
