GLSA-200802-05 : Gnumeric: User-assisted execution of arbitrary code
High Nessus Plugin ID 31083
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200802-05 (Gnumeric: User-assisted execution of arbitrary code)
Multiple integer overflow and signedness errors have been reported in the excel_read_HLINK() function in file plugins/excel/ms-excel-read.c when processing XLS HLINK opcodes.
A remote attacker could entice a user to open a specially crafted XLS file, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll Gnumeric users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-office/gnumeric-1.8.1'
