GStreamer is a streaming media framework based on graphs of filters which operate on media data. The gstreamer1-plugins-base packages contain a collection of well-maintained base plug-ins.

Security Fix(es):

* gstreamer: GStreamer: Arbitrary code execution via OGG file parsing buffer overflow (CVE-2026-18297)
* gstreamer1-plugins-base: gstreamer: NULL/invalid-pointer dereference in gst_rtsp_message_parse_auth_credentials() when parsing a crafted Digest Authorization/WWW-Authenticate header (CVE-2026-85150)

CVE-2026-18297
GStreamer OGG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of OGG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29584.
CVE-2026-85150
A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.
