X.Org X11 TOG-CUP extension information disclosure
| xorg-togcup-information-disclosure (39761) |  Low Risk |
Description:
X.Org X11 could allow a remote attacker to obtain sensitive information, caused by an array index error in the ProcGetReservedColormapEntries() function within the TOG-CUP extension. If the X server is configured for TCP connections, a remote attacker could exploit this vulnerability to disclose arbitrary memory and other sensitive information.
