openSUSE Security Update : libgit2 (openSUSE-2018-1314)
Medium Nessus Plugin ID 118486
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis update for libgit2 fixes the following issues :
- CVE-2018-8099: Fixed possible denial of service attack
via different vectors by not being able to differentiate
between these status codes (bsc#1085256).
- CVE-2018-11235: 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. (bsc#1095219)
- CVE-2018-10887: It has been discovered that an
unexpected sign extension in git_delta_apply function in
delta.c file may have lead to an integer overflow which
in turn leads to an out of bound read, allowing to read
before the base object. An attacker could have used this
flaw to leak memory addresses or cause a Denial of
- CVE-2018-10888: A missing check in git_delta_apply
function in delta.c file, may lead to an out-of-bound
read while reading a binary delta file. An attacker may
use this flaw to cause a Denial of Service.
- CVE-2018-15501: A remote attacker can send a crafted
smart-protocol 'ng' packet that lacks a '\0' byte to
trigger an out-of-bounds read that leads to DoS.
