printf: incorrect output for integers with thousands separator and width field
|
||||
|
||||
When the printf family of functions is called with a format specifier
|
||||
that uses an <apostrophe> (enable grouping) and a minimum width
|
||||
specifier, the resulting output could be larger than reasonably expected
|
||||
by a caller that computed a tight bound on the buffer size. The
|
||||
resulting larger than expected output could result in a buffer overflow
|
||||
in the printf family of functions.

getaddrinfo: Stack read overflow in no-aaaa mode
|

|

If the system is configured in no-aaaa mode via /etc/resolv.conf,

getaddrinfo is called for the AF_UNSPEC address family, and a DNS
|

response is received over TCP that is larger than 2048 bytes,

tunables: local privilege escalation through buffer overflow

ISO-2022-CN-EXT: fix out-of-bound writes when writing escape sequence
|

|
||||
The iconv() function in the GNU C Library versions 2.39 and older may
|
||||
overflow the output buffer passed to it by up to 4 bytes when converting
|
||||
strings to the ISO-2022-CN-EXT character set, which may be used to
|
||||
crash an application or overwrite a neighbouring variable.
|
||||
|
||||
ISO-2022-CN-EXT uses escape sequences to indicate character set changes
|
||||
(as specified by RFC 1922). While the SOdesignation has the expected
|
||||
bounds checks, neither SS2designation nor SS3designation have its;
|
||||
allowing a write overflow of 1, 2, or 3 bytes with fixed values:
|
||||
'$+I', '$+J', '$+K', '$+L', '$+M', or '$*H'.

nscd: netgroup cache may terminate daemon on memory allocation failure
|
||||
|
||||
The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or
|
||||
xrealloc and these functions may terminate the process due to a memory
|
||||
allocation failure resulting in a denial of service to the clients. The
|
||||
flaw was introduced in glibc 2.15 when the cache was added to nscd.
|
||||
|
||||
This vulnerability is only present in the nscd binary.
|
||||
|
||||
Subsequent refactoring of the netgroup cache only added more uses of
|
||||
xmalloc and xrealloc. Uses of xmalloc and xrealloc in other parts of
|
||||
nscd only occur during startup of the daemon and so are not affected by
|
||||
client requests that could trigger an out of memory followed by
|
||||
termination.
|
||||
|
||||

nscd: netgroup cache assumes NSS callback uses in-buffer strings
|
||||
|
||||
The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory
|
||||
when the NSS callback does not store all strings in the provided buffer.
|
||||
The flaw was introduced in glibc 2.15 when the cache was added to nscd.
|
||||
|
||||
This vulnerability is only present in the nscd binary.
|
||||
|
||||
There is no guarantee from the NSS callback API that the returned
|
||||
strings are all within the buffer. However, the netgroup cache code
|
||||
assumes that the NSS callback uses in-buffer strings and if it doesn't
|
||||
the buffer resizing logic could lead to potential memory corruption.

GNU C Library Security Advisory Format
|
||||
======================================
|
||||
|
||||
Security advisories in this directory follow a simple git commit log
|
||||
format, with a heading and free-format description augmented with tags
|
||||
to allow parsing key information. References to code changes are
|
||||
specific to the glibc repository and follow a specific format:
|
||||
|
||||
Tag-name: <commit-ref> (release-version)
|
||||
|
||||
The <commit-ref> indicates a specific commit in the repository. The
|
||||
release-version indicates the publicly consumable release in which this
|
||||
commit is known to exist. The release-version is derived from the
|
||||
git-describe format, (i.e. stripped out from glibc-2.34.NNN-gxxxx) and
|
||||
is of the form 2.34-NNN. If the -NNN suffix is absent, it means that
|
||||
the change is in that release tarball, otherwise the change is on the
|
||||
release/2.YY/master branch and not in any released tarball.
|
||||
|
||||
The following tags are currently being used:
|
||||
|
||||
CVE-Id:
|
||||
This is the CVE-Id assigned under the CVE Program
|
||||
(https://www.cve.org/).
|
||||
|
||||
Public-Date:
|
||||
The date this issue became publicly known.
|
||||
|
||||
Vulnerable-Commit:
|
||||
The commit that introduced this vulnerability. There could be multiple
|
||||
entries, one for each release branch in the glibc repository; the
|
||||
release-version portion of this tag should tell you which branch this is
|
||||
on.
|
||||
|
||||
Fix-Commit:
|
||||
The commit that fixed this vulnerability. There could be multiple
|
||||
entries for each release branch in the glibc repository, indicating that
|
||||
all of those commits contributed to fixing that issue in each of those
|
||||
branches.
|
||||
|
||||
Reported-By:
|
||||
The entity that reported this issue. There could be multiple entries, one for
|
||||
each reporter.
|
||||
|
||||
Adding an Advisory
|
||||
------------------
|
||||
|
||||
An advisory for a CVE needs to be added on the master branch in two steps:
|
||||
|
||||
1. Add the text of the advisory without any Fix-Commit tags along with
|
||||
the fix for the CVE. Add the Vulnerable-Commit tag, if applicable.
|
||||
The advisories directory does not exist in release branches, so keep
|
||||
the advisory text commit distinct from the code changes, to ease
|
||||
backports. Ask for the GLIBC-SA advisory number from the security
|
||||
team.
|
||||
|
||||
2. Finish all backports on release branches and then back on the msater
|
||||
branch, add all commit refs to the advisory using the Fix-Commit
|
||||
tags. Don't bother adding the release-version subscript since the
|
||||
next step will overwrite it.
|
||||
|
||||
3. Run the process-advisories.sh script in the scripts directory on the
|
||||
advisory:
|
||||
|
||||
scripts/process-advisories.sh update GLIBC-SA-YYYY-NNNN
|
||||
|
||||
(replace YYYY-NNNN with the actual advisory number).
|
||||
|
||||
4. Verify the updated advisory and push the result.
|
||||
|
||||
Getting a NEWS snippet from advisories
|
||||
--------------------------------------
|
||||
|
||||
Run:
|
||||
|
||||
scripts/process-advisories.sh news
|
||||
|
||||
and copy the content into the NEWS file.
