Netatalk is a kernel level implementation of the AppleTalk Protocol Suite, which allows Unix hosts to act as file, print, and time servers for Apple computers. It includes several script utilities, including etc2ps.sh.
Multiple vulnerabilities have been discovered in Netatalk. Please review the CVE identifiers referenced below for details.
Please review the referenced CVE identifiers for details.
There is no known workaround at this time.
All Netatalk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/netatalk-3.1.18"
The etc2ps.sh script, included in the Netatalk package, is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files with the rights of the user running the utility.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-fs/netatalk | * | < 1.6.4-r1 | >= 1.6.4-r1 |
Netatalk is a kernel level implementation of the AppleTalk Protocol Suite, which allows Unix hosts to act as file, print, and time servers for Apple computers. It includes several script utilities, including etc2ps.sh.
The etc2ps.sh script creates temporary files in world-writeable directories with predictable names.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When etc2ps.sh is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
There is no known workaround at this time.
All Netatalk users should upgrade to the latest version:
# emerge sync # emerge -pv ">=net-fs/netatalk-1.6.4-r1" # emerge ">=net-fs/netatalk-1.6.4-r1"
