Advisories MDKSA-2007-005: Updated xorg-x11/XFree86 packages fix integer overflow vulnerabilities

[paul]

Sean Larsson of iDefense Labs discovered several vulnerabilities in

X.Org/XFree86:

 

Local exploitation of a memory corruption vulnerability in the

'ProcRenderAddGlyphs()' function in the X.Org and XFree86 X server

could allow an attacker to execute arbitrary code with privileges of

the X server, typically root. (CVE-2006-6101)

 

Local exploitation of a memory corruption vulnerability in the

'ProcDbeGetVisualInfo()' function in the X.Org and XFree86 X server

could allow an attacker to execute arbitrary code with privileges of

the X server, typically root. (CVE-2006-6102)

 

Local exploitation of a memory corruption vulnerability in the

'ProcDbeSwapBuffers()' function in the X.Org and XFree86 X server could

allow an attacker to execute arbitrary code with privileges of the X

server, typically root. (CVE-2006-6103)

 

Updated packages are patched to address these issues.
