Description

This security bulletin contains information about 5 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2026-85150)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to a null pointer dereference in the RTSP message parser of gst-plugins-base when parsing authentication credentials in a crafted RTSP Authorization header. A remote attacker can send a specially crafted Authorization header to an RTSP server or an application using the RTSP message parser to cause a denial of service.


2) Out-of-bounds write (CVE-ID: N/A)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds read and write operations in the FFmpeg audio decoder and encoder elements in gst-libav when processing a crafted media file with more than 64 audio channels. A remote attacker can supply a crafted media file with more than 64 audio channels to cause a denial of service.


3) Insertion of Sensitive Information Into Sent Data (CVE-ID: N/A)

CWE-ID: CWE-201 - Insertion of Sensitive Information Into Sent Data

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to improper handling of sensitive information during cross-origin redirects in the souphttpsrc HTTP source when automatically following cross-origin HTTP redirects. A remote attacker can redirect the request to an attacker-controlled endpoint to disclose sensitive information.

Exploitation requires an application to open an attacker-controlled initial HTTP location with credentials, cookies, or custom headers configured.


4) Integer overflow (CVE-ID: N/A)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to integer overflow in the CEA-608 closed caption parser of the MOV/MP4 demuxer (qtdemux) when parsing caption sample data containing multiple atoms. A remote attacker can provide a crafted MP4 or MOV file to disclose sensitive information.


5) Numeric Truncation Error (CVE-ID: N/A)

CWE-ID: CWE-197 - Numeric Truncation Error

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to integer truncation in the CEA-608 closed caption parser of the MOV/MP4 demuxer (qtdemux) when converting caption sample data with a large length value. A remote attacker can provide a crafted MP4 or MOV file to disclose sensitive information.
