CVE-2018-10888 (2018-07-10)

A flaw was found in libgit2 before version 0.27.3. 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-2018-10887 (2018-07-10)

A flaw was found in libgit2 before version 0.27.3. It has been discovered that an unexpected sign extension in git_delta_apply function in delta.c file may lead to an integer overflow which in turn leads to an out of bound read, allowing to read before the base object. An attacker may use this flaw to leak memory addresses or cause a Denial of Service.

CVE-2018-25032 (2022-03-25)

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
