Vulnerabilities and false positives strike major products.
Symantec
users have been warned of some serious issues with archive handling, across a wide range of software produced by the company, which could be used to caused denial of service or even breach a system.
AVG
, meanwhile, has also been hit by a less serious vulnerability, along with a string of reports of false positives.
The
Symantec
flaws, both involving data checking errors in the
Symantec Decomposer
module when processing RAR and CAB archives, affects a wide set of the company’s security products, including the corporate
Symantec Antivirus
and home-user
Norton
ranges, and
Brightmail
spam filters. Full details of affected products from
Symantec
are

.
Symantec
was first informed of the problems in November, and patches have been released to customers, who should be protected by automatic updates. A
Secunia
alert, rating the issues ‘Highly Critical’, is
here
.
Grisoft
has also issued patches for a vulnerability in its
AVG
product, this time far less severe and only allowing local users to escalate privileges (see a
Secunia
bulletin
here
). Developers there have also been kept busy with a series of false positive reports, with problems with
SendPhotos
and
World of Warcraft
followed by several recent reports of the product identifying installer components of
Google
‘s
Desktop Search
product as a possible trojan. Both issues are thought to affect both licensed versions and the popular free version of
AVG
.
As always users are advised to ensure they are running the latest versions of all security software.
