| CVE-2026-42369 | Cri | 0.65 | 10.0 | 0.00 | May 4, 2026 | GV-VMS V20 is a Video Monitoring Software used to gather the feeds of many surveillance cameras and manage other security devices. It is a native application accessed locally, but it is also possible to enable remote access via the "WebCam Server" feature. Once enabled, it is possible to access to the management and monitoring feature via a regular Web interface. This webersever is another native application, compiled without ASLR, which makes exploitation much easier and more likely. Most of the features require authentication before being reachable and leverage a standard login page to grant access. However the `gvapi` endpoint uses its own authentication mechanism via an `HTTP Authorization` header. It supports both `Basic` authentication and the `Digest` modes of authentication. #### Stack-overflow via unbound copy of base64 decoded string The `b64decoder` string is sized dynamically, but it is then copied to the `Buffer` stack variable one character at the time at [0], and there's no bound-check. As such, if the decoded string is bigger than 256 characters (the size of the `Buffer` variable) then a stack overflow occurs. Because the data can be fully controlled by an attacker and lack of ASLR, this vulnerability can easily be exploited to gain full code execution as SYSTEM on the machine running the service. | |
| CVE-2004-1717 | 0.05 | — | 0.25 | Aug 16, 2004 | Multiple buffer overflows in the psscan function in ps.c for gv (ghostview) allow remote attackers to execute arbitrary code via a Postscript file with a long (1) BoundingBox, (2) comment, (3) Orientation, (4) PageOrder, or (5) Pages value. | ||
| CVE-2002-0838 | 0.03 | — | 0.04 | Oct 10, 2002 | Buffer overflow in (1) gv 3.5.8 and earlier, (2) gvv 1.0.2 and earlier, (3) ggv 1.99.90 and earlier, (4) gnome-gv, and (5) kghostview in kdegraphics 2.2.2 and earlier, allows attackers to execute arbitrary code via a malformed (a) PDF or (b) PostScript file, which is processed by an unsafe call to sscanf. | ||
| CVE-2002-1569 | 0.00 | — | 0.03 | Nov 17, 2003 | gv 3.5.8, and possibly earlier versions, allows remote attackers to execute arbitrary commands via shell metacharacters in the filename for (1) a PDF file or (2) a gzip file. |
