Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: High

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 10 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

This update for live555 fixes the following issues: Changes in live555: - Update to version 2026.08.25: * Fixed a bug in "VorbisAudioRTPSource" that could have caused a malicious SDP description to crash a RTP client. - update to 2026.08.14: * Fixed a bug that could cause a problem with subclassed variants of H.264 or H.265 RTP sinks. * Fixed old code in "GroupsockHelper.cpp" that was using hardcoded numeric error numbers * Fixed a memory leak that could occur when parsing a SDP description that contains two or more * When adding protection against the use of 'stolen' RTSP session ids we forgot to do so for every "SETUP" command. This release fixes that. * Fixed a typo in "RTSPCommon.cpp": "smtpe" -> "smpte". * Updated the RTSP server implementation to return a "Unsupported Transport" error if a "SETUP" request does not include a "Transport:" header. * Added "-std=c++20" to the "CPLUSPLUS_FLAGS" line in each "config.*" file, so that "std::atomic_flag::test" will compile with compilers that support * Made the parsing of MP3 audio files more robust to protect against malformed MP3 data. * Minor change to "testProgs/testRTSPClient.cpp" to make compiling on Mac OS X happier. - Update to version 2026.06.01: * Updated the "RTSPServer" implementation of the "SETUP" command to make it more robust if subclassed code reimplements "lookupServerMediaSession()" as an asynchronous operation. - update to 2026.05.30: * Updated the "RTSPServer" implementation some more to make it more robust if subclassed code reimplements "lookpServerMediaSession()" as an asynchronous operation. * Added an (integer) index to identify each server's 'client connection', and changed the "fClientConnections" table to be indexed by this id. * In the "RTSPServer" implementation, removed the "fOurClientConnection" member variable. This had been left over from when the RTSP "SETUP" command had been implemented as a single, synchronous function. Now that "SETUP" is implemented using multiple functions, possibly asynchronously (depending upon how "lookpServerMediaSession()" is implemented), this member variable was potentially dangerous if more than one "SETUP" is performed concurrently on the same client connection, or on separate client connections. - update to 2026.05.28: * fix use-after-free memory corruption introduced in fix for CVE-2026-41470 - Update to version 2026.04.22 (CVE-2026-41470, boo#1265856): * Added extra checking to the handling of the RTSP server's "PLAY", "PAUSE", "TEARDOWN", and "SET_PARAMETER" commands, to ensure that, if the session is authenticated, then a proper authentication check is done before these commands are handled. This protects against the use of a 'stolen' RTSP session id to send these commands. (Note, however, that if the session is not authenticated (i.e., no username,password is needed), then no such protection is possible.) - Changes from version 2026-04-01: * Updated the way that the RTSP server generates successive RTSP 'session ids' to make it less likely that an attacker could guess a session id. * Updated the RTSP server implementation to make it possible for a client to request both interleaved (i.e., RTP/RTCP-over-TCP) and non-interleaved (i.e., RTP/RTCP-over-UDP) delivery within the same session. - Update to version 2026.03.23 (boo#1279932): * CVE-2026-38998: Fixed a bug in the RTSP server code that caused it to improperly handle non-interleaved "SETUP"s that were sent for a session where interleaving (i.e., RTP/RTCP-over-TCP) had already been "SETUP". (This could cause a 'use-after-free' error. * For changes between 2024.08.01 to today, please refer to https://download.live555.com/changelog.txt - update to 2024-08-01: * Updated "ServerMediaSession::generateSDPDescription()" to treat "time_t" as (long long).
