Title: xSANE Insecure Temporary File Creation Vulnerability
Severity: MODERATE
Description:
xSANE is a graphical program used to communicate with scanners and digital video devices. It uses the SANE library to communicate with physical devices.
xSANE creates temporary files in the /tmp directory during the scanning process. Temporary files are also used to communicate with the SANE processes when images are previewed or saved.
xSANE uses the mktemp(3) library call, which creates files with predictable names. It is possible for a local attacker to create symbolic links with these file names. When a local user executes xSANE, arbitrary files may be overwritten.
Earlier versions of xSANE may also be vulnerable.
