GLSA-200705-11 : MySQL: Two Denial of Service vulnerabilities
Low Nessus Plugin ID 25188
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200705-11 (MySQL: Two Denial of Service vulnerabilities)
mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when processing certain types of SQL requests. Sec Consult also discovered another NULL pointer dereference when sorting certain types of queries on the database metadata.
In both cases, a remote attacker could send a specially crafted SQL request to the server, possibly resulting in a server crash. Note that the attacker needs the ability to execute SELECT queries.
There is no known workaround at this time.
SolutionAll MySQL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-db/mysql-5.0.38'
