GLSA: 200311-02
package: net-www/opera
summary: Buffer overflows in Opera 7.11 and 7.20
severity: high
Gentoo bug: 31775
date: 2003-11-19
CVE: CAN-2003-0870
exploit: local / remote
affected: =7.11
affected: =7.20
fixed: >=7.21
DESCRIPTION:
The Opera browser can cause a buffer allocated on the heap to overflow under
certain HREFs when rendering HTML. The mail system is also deemed vulnerable
and an attacker can send an email containing a malformed HREF, or plant the
malicious HREF on a web site.
Please see http://www.atstake.com/research/advisories/2003/a102003-1.txt for
further details.
SOLUTION:
Users are encouraged to perform an 'emerge --sync' and upgrade the package to
the latest available version. Opera 7.22 is recommended as Opera 7.21 is
vulnerable to other security flaws. Specific steps to upgrade:
emerge --sync
emerge '>=net-www/opera-7.22'
emerge clean
