Description Paweł Hajdan, Jr. (RETIRED) gentoo-dev 2011-03-22 09:37:30 UTC
A vulnerability has been discovered in libzip, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL pointer dereference error within the "_zip_name_locate()" function in lib/zip_name_locate.c, which can be exploited to cause a crash by e.g. tricking an application using the "zip_name_locate()" function with the "ZIP_FL_UNCHANGED" flag into processing an empty ZIP file.

The vulnerability is confirmed in version 0.9.3. Prior versions may also be affected.

Update to version 0.10.

I added you the 0.10 into the main tree.
But given that it is 1 year of development worth i would rather see others test it first prior stabilising it.
