GLSA-200410-02 : Netpbm: Multiple temporary file issues
Low Nessus Plugin ID 15418
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200410-02 (Netpbm: Multiple temporary file issues)
Utilities contained in the Netpbm package prior to the 9.25 version contain defects in temporary file handling. They create temporary files with predictable names without checking first that the target file doesn't already exist.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When a user or a tool calls one of the affected utilities, this would result in file overwriting with the rights of the user running the utility.
There is no known workaround at this time.
SolutionAll Netpbm users should upgrade to an unaffected version:
# emerge sync # emerge -pv '>=media-libs/netpbm-10.0' # emerge '>=media-libs/netpbm-10.0'
