[slackware-security] git (SSA:2023-018-01)
New git packages are available for Slackware 14.0, 14.1, 14.2, 15.0,
and -current to fix security issues.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/git-2.35.6-i586-1_slack15.0.txz: Upgraded.
This release fixes two security issues:
* CVE-2022-41903:
git log has the ability to display commits using an arbitrary
format with its --format specifiers. This functionality is also
exposed to git archive via the export-subst gitattribute.
When processing the padding operators (e.g., %<(, %<|(, %>(,
%>>(, or %><( ), an integer overflow can occur in
pretty.c::format_and_pad_commit() where a size_t is improperly
stored as an int, and then added as an offset to a subsequent
memcpy() call.
This overflow can be triggered directly by a user running a
command which invokes the commit formatting machinery (e.g., git
log --format=...). It may also be triggered indirectly through
git archive via the export-subst mechanism, which expands format
specifiers inside of files within the repository during a git
archive.
This integer overflow can result in arbitrary heap writes, which
may result in remote code execution.
* CVE-2022-23521:
gitattributes are a mechanism to allow defining attributes for
paths. These attributes can be defined by adding a `.gitattributes`
file to the repository, which contains a set of file patterns and
the attributes that should be set for paths matching this pattern.
When parsing gitattributes, multiple integer overflows can occur
when there is a huge number of path patterns, a huge number of
attributes for a single pattern, or when the declared attribute
names are huge.
These overflows can be triggered via a crafted `.gitattributes` file
that may be part of the commit history. Git silently splits lines
longer than 2KB when parsing gitattributes from a file, but not when
parsing them from the index. Consequentially, the failure mode
depends on whether the file exists in the working tree, the index or
both.
This integer overflow can result in arbitrary heap reads and writes,
which may result in remote code execution.
