Detailsinfo

A vulnerability classified as problematic has been found in Red Hat Enterprise Linux 10, Enterprise Linux 6, Enterprise Linux 7, Enterprise Linux 8 and Enterprise Linux 9. Affected is some unknown functionality of the component DTLS Plugin. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on availability. CVE summarizes:

A stack buffer overflow vulnerability was found in GStreamer's DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.

The advisory is available at access.redhat.com. This vulnerability is traded as CVE-2026-59692 since 07/06/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 07/09/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
