Page 2 / 2
7.5 CVSS

Integer signedness errors in XFree86 4.1.0 allow remote attackers to cause a denial of service and possibly execute arbitrary code when using the GLX extension and Direct Rendering Infrastructure (DRI).

EPSS: 3.10%
10.0 CVSS
CVE-2004-0083
Exploit Found

Buffer overflow in ReadFontAlias from dirfile.c of XFree86 4.1.0 through 4.3.0 allows local users and remote attackers to execute arbitrary code via a font alias file (font.alias) with a long token, a different vulnerability than CVE-2004-0084 and CVE-2004-0106.

EPSS: 21.18%
10.0 CVSS
CVE-2004-0084
Exploit Found

Buffer overflow in the ReadFontAlias function in XFree86 4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows local or remote authenticated users to execute arbitrary code via a malformed entry in the font alias (font.alias) file, a different vulnerability than CVE-2004-0083 and CVE-2004-0106.

EPSS: 24.86%
7.2 CVSS

Multiple unknown vulnerabilities in XFree86 4.1.0 to 4.3.0, related to improper handling of font files, a different set of vulnerabilities than CVE-2004-0083 and CVE-2004-0084.

EPSS: 0.43%
7.5 CVSS

Multiple integer overflows in the font libraries for XFree86 4.3.0 allow local or remote attackers to cause a denial of service or execute arbitrary code via heap-based and stack-based buffer overflow attacks.

EPSS: 5.85%
7.3 CVSS

The xterm terminal emulator in XFree86 4.2.0 and earlier allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.

EPSS: 3.40%
2.1 CVSS

The DEC UDK processing feature in the xterm terminal emulator in XFree86 4.2.99.4 and earlier allows attackers to cause a denial of service via a certain character escape sequence that causes the terminal to enter a tight loop.

EPSS: 0.42%
7.2 CVSS

Untrusted search path vulnerability in libX11.so in xfree86, when used in setuid or setgid programs, allows local users to gain root privileges via a modified LD_PRELOAD environment variable that points to a malicious module.

EPSS: 0.37%
10.0 CVSS

xdm, with the authComplain variable set to false, allows arbitrary attackers to connect to the X server if the xdm auth directory does not exist.

EPSS: 1.97%
7.5 CVSS
CVE-2002-1317
Exploit Found

Buffer overflow in Dispatch() routine for XFS font server (fs.auto) on Solaris 2.5.1 through 9 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a certain XFS query.

EPSS: 24.03%
