Buffer Overflow in X.Org Xserver and Associated Libraries Affecting Sun Microsystems

CVE-2008-0006

What is CVE-2008-0006?

A buffer overflow vulnerability exists in the X.Org Xserver and the libfont and libXfont libraries. This flaw occurs due to improper validation of the values in the PCF_BDF_ENCODINGS table when processing PCF fonts with a significant difference between the last and first column values. Exploitation of this vulnerability may allow attackers to execute arbitrary code in the context of the user running the Xserver, potentially leading to a complete system compromise on affected platforms including Sun Solaris. This vulnerability underscores the importance of keeping software updated and implementing security best practices to defend against unauthorized access.
