CVE-2015-2776 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-2776): The parse_SST function in FreeXL before 1.0.0i allows remote attackers to cause a denial of service (memory consumption) via a crafted shared strings table in a workbook. CVE-2015-2754 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-2754): FreeXL before 1.0.0i allows remote attackers to cause a denial of service (stack corruption) and possibly execute arbitrary code via a crafted workbook, related to a "premature EOF." CVE-2015-2753 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-2753): FreeXL before 1.0.0i allows remote attackers to cause a denial of service (stack corruption) or possibly execute arbitrary code via a crafted sector in a workbook. Bug has been around since March, with upstream released 2015-03-22. Any progress with Ebuild? We are now in August, this is a B2 bug, which should be fixed. This has been around since the March of this year. Please advised if you still want to maintain this package, or remove it from tree. Hey, working on it.

From ${URL} : I found multiple issues in the library FreeXL 1.0.0g. The vendor has corrected these issues in FreeXL 1.0.1 , and a diff for the four issues is available here: https://www.gaia-gis.it/fossil/freexl/fdiff?v1=2e167b337481dda3&v2=61618ce51a9b0c15&sbs=1 FreeXL 1.0.1 itself has been released here: http://www.gaia-gis.it/gaia-sins/freexl-1.0.1.tar.gz To reproduce: ./test_xl $reproducer #1: A flaw was found in the way FreeXL reads sectors from the input file. A specially crafted file could possibly result in stack corruption near freexl.c:3752. Reproducer: https://www.dropbox.com/s/3htzndywvtmomlx/freexl_9f74b0e8?dl=0 #2: A flaw was found in the function allocate_cells(). A specially crafted file with invalid workbook dimensions could possibly result in stack corruption near freexl.c:1074 Reproducer: https://www.dropbox.com/s/dcnbbntf7lp03yn/freexl_c9be2aa7?dl=0 #3: A flaw was found in the way FreeXL handles a premature EOF. A specially crafted input file could possibly result in stack corruption near freexl.c:1131 Reproducer: https://www.dropbox.com/s/66srfory903w6cl/freexl_d7273f72?dl=0 #4: FreeXL 1.0.0g did not properly check requests for workbook memory allocation. A specially crafted input file could cause a Denial of Service, or possibly write onto the stack. Reproducer (ulimit -Sv 128000): https://www.dropbox.com/s/gh61gzaf8jj30hj/freexl_6889d18b?dl=0 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
