Security update for libgit2
Description of the patch
This update for libgit2 to version 0.26.5 fixes the following issues:
The following security vulnerabilities were addressed:
- CVE-2018-10887: Fixed an integer overflow which in turn leads to an out of
bound read, allowing to read the base object, which could be exploited by
an attacker to cause denial of service (DoS) (bsc#1100613).
- CVE-2018-10888: Fixed an out-of-bound read while reading a binary delta file,
which could be exploited by an attacker t ocause a denial of service (DoS)
(bsc#1100612).
- CVE-2018-11235: Fixed a remote code execution, which could occur with a
crafted .gitmodules file (bsc#1095219)
- CVE-2018-15501: Prevent out-of-bounds reads when processing smart-protocol 'ng' packets
(bsc#1104641)

With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs \"git clone --recurse-submodules\" because submodule \"names\" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with \"../\" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.",
