Buffer overflow in the git_pkt_parse_line function in transports/smart_pkt.c in the Git Smart Protocol support in libgit2 before 0.24.6 and 0.25.x before 0.25.1 allows remote attackers to have unspecified impact via a crafted non-flush packet.

This update for libgit2 fixes the several issues.

These security issues were fixed :

  - CVE-2016-10128: Additional sanitization prevent some     edge cases in the Git Smart Protocol which can lead to     reading outside of a buffer (bsc#1019036).

  - CVE-2016-10129: Additional sanitization prevent some     edge cases in the Git Smart Protocol which can lead to     reading outside of a buffer (bsc#1019036).

  - CVE-2016-10130: When using the custom certificate     callback or when using pygit2 or git2go a attacker could     have caused an invalid certificate to be accepted     (bsc#1019037).

  - CVE-2017-5338: When using the custom certificate     callback or when using pygit2 or git2go a attacker could     have caused an invalid certificate to be accepted     (bsc#1019037).

  - CVE-2017-5339: When using the custom certificate     callback or when using pygit2 or git2go a attacker could     have caused an invalid certificate to be accepted     (bsc#1019037).
