A vulnerability in Bash may allow users to escalate privileges.
|Package||app-shells/bash on all architectures|
|Affected versions||< 5.0_p11-r1|
|Unaffected versions||>= 5.0_p11-r1|
Bash is the standard GNU Bourne Again SHell.
It was discovered that Bash incorrectly dropped privileges by setting its effective UID to its real UID.
A local attacker could possibly escalate privileges.
There is no known workaround at this time.
All Bash users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-shells/bash-5.0_p11-r1"
