Synopsis
The X.Org X11 library contains multiple integer overflows, which could lead to the execution of arbitrary code.Background
X.Org is an implementation of the X Window System. The X.Org X11 library provides the X11 protocol library files.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
x11-libs/libX11 | < 1.0.3-r2 | >= 1.0.3-r2 | All supported architectures |
Description
Multiple integer overflows have been reported in the XGetPixel() function of the X.Org X11 library.
Impact
By enticing a user to open a specially crafted image, an attacker could cause a Denial of Service or an integer overflow, potentially resulting in the execution of arbitrary code with root privileges.
Workaround
There is no known workaround at this time.
Resolution
All X.Org X11 library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/libX11-1.0.3-r2"
