One of the requirements to becoming a CVE Numbering Authority (CNA) is to publish advisories. Do this by maintaining a file for each CVE fixed in the advisories directory in the source tree. Links to the advisories can then be shared as: https://sourceware.org/git/?p=glibc.git;a=blob_plain;f=advisories/GLIBC-SA-YYYY-NNNN The file format at the moment is rudimentary and derives from the git commit format, i.e. a subject line and a potentially multi-paragraph description and then tags to describe some meta information. This is a loose format at the moment and could change as we evolve this. Also add a script process-fixed-cves.sh that processes these advisories and generates a list to add to NEWS at release time.

tunables: local privilege escalation through buffer overflow
|
|
|
|
If a tunable of the form NAME=NAME=VAL is passed in the environment of a
|
|
setuid program and NAME is valid, it may result in a buffer overflow,
|
|
which could be exploited to achieve escalated privileges. This flaw was
|
|
introduced in glibc 2.34.
