Package        : libgit2
Version        : 0.21.1-3+deb8u1
CVE ID         : CVE-2018-10887 CVE-2018-10888 CVE-2018-15501


CVE-2018-15501
     A potential out-of-bounds read when processing a "ng" smart packet
     might lead to a Denial of Service.

CVE-2018-10887
     A flaw has been discovered that may lead to an integer overflow which
     in turn leads to an out of bound read, allowing to read before the
     base object. This might be used to leak memory addresses or cause a
     Denial of Service.

CVE-2018-10888
     A flaw may lead to an out-of-bound read while reading a binary delta
     file. This might result in a Denial of Service.


For Debian 8 "Jessie", these problems have been fixed in version
0.21.1-3+deb8u1.

We recommend that you upgrade your libgit2 packages.
