GLSA-200405-18 : Buffer Overflow in Firebird
Medium Nessus Plugin ID 14504
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200405-18 (Buffer Overflow in Firebird)
A buffer overflow exists in three Firebird binaries (gds_inet_server, gds_lock_mgr, and gds_drop) that is exploitable by setting a large value to the INTERBASE environment variable.
An attacker could control program execution, allowing privilege escalation to the UID of Firebird, full access to Firebird databases, and trojaning the Firebird binaries. An attacker could use this to compromise other user or root accounts.
There is no known workaround.
SolutionAll users should upgrade to the latest version of Firebird:
# emerge sync # emerge -pv '>=dev-db/firebird-1.5' # emerge '>=dev-db/firebird-1.5'
