CVE-2019-1348

An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, and v2.14.6. The --export-marks option of git fast-import is exposed also via the in-stream command feature export-marks=... and it allows overwriting arbitrary paths.

libgit2 has been updated to version 0.28.4 to fix several security issues:

• A carefully constructed commit object with a very large number of parents may lead to potential out-of-bounds writes or potential denial of service.

• CVE-2019-1348: the fast-import stream command "feature export-marks=path" allows writing to arbitrary file paths. As libgit2 does not offer any interface for fast-import, it is not susceptible to this vulnerability.

• CVE-2019-1350: recursive clones may lead to arbitrary remote code executing due to improper quoting of command line arguments. As libgit2 uses libssh2, which does not require us to perform command line parsing, it is not susceptible to this vulnerability.

• CVE-2019-1387: it is possible to let a submodule's git directory point into a sibling's submodule directory, which may result in overwriting parts of the Git repository and thus lead to arbitrary command execution. As libgit2 doesn't provide any way to do submodule clones natively, it is not susceptible to this vulnerability. Users of libgit2 that have implemented recursive submodule clones manually are encouraged to review their implementation for this vulnerability.

The updated packages fix security vulnerabilities:

The --export-marks option of git fast-import is exposed also via the in-stream command feature export-marks=... and it allows overwriting arbitrary paths. (CVE-2019-1348)

When submodules are cloned recursively, under certain circumstances Git could be fooled into using the same Git directory twice. We now require the directory to be empty. (CVE-2019-1349)

Recursive clones are currently affected by a vulnerability that is caused by too-lax validation of submodule names, allowing very targeted attacks via remote code execution in recursive clones. (CVE-2019-1387)

Arbitrary command execution is possible in Git before 2.21.1, because a "git submodule update" operation can run commands found in the .gitmodules file of a malicious repository. (CVE-2019-19604)

This update for git fixes the following issues:

Security issues fixed:

• CVE-2019-1349: Fixed issue on Windows, when submodules are cloned recursively, under certain circumstances Git could be fooled into using the same Git directory twice (bsc#1158787).

Bug fixes:

This update for git fixes the following issues:

Security issues fixed:

• CVE-2020-11008: Specially crafted URLs may have tricked the credentials helper to providing credential information that is not appropriate for the protocol in use and host being contacted (bsc#1169936)

git was updated to 2.26.1 (bsc#1169786, jsc#ECO-1628, bsc#1149792)

• Fix git-daemon not starting after conversion from sysvinit to systemd service (bsc#1169605).

• CVE-2020-5260: Specially crafted URLs with newline characters could have been used to make the Git client to send credential information for a wrong host to the attacker's site bsc#1168930

git 2.26.0 (bsc#1167890, jsc#SLE-11608):

• 'git rebase' now uses a different backend that is based on the 'merge' machinery by default. The 'rebase.backend' configuration variable reverts to old behaviour when set to 'apply'
• Improved handling of sparse checkouts
• Improvements to many commands and internal features

git 2.25.2:

• bug fixes to various subcommands in specific operations

git 2.25.1:

• 'git commit' now honors advise.statusHints
• various updates, bug fixes and documentation updates

git 2.25.0

• The branch description ('git branch --edit-description') has been used to fill the body of the cover letters by the format-patch command; this has been enhanced so that the subject can also be filled.
• A few commands learned to take the pathspec from the standard input or a named file, instead of taking it as the command line arguments, with the '--pathspec-from-file' option.
• Test updates to prepare for SHA-2 transition continues.
• Redo 'git name-rev' to avoid recursive calls.
• When all files from some subdirectory were renamed to the root directory, the directory rename heuristics would fail to detect that as a rename/merge of the subdirectory to the root directory, which has been corrected.
• HTTP transport had possible allocator/deallocator mismatch, which has been corrected.

git 2.23.0:

• The '--base' option of 'format-patch' computed the patch-ids for prerequisite patches in an unstable…
