[CCID News] On October 25, Linux manufacturers were attacked by two new security viruses, a series of graphics decoders and GAIM instant messaging clients affected.
According to the largest Linux developer Red Hat, hackers have begun to use fraudulent emails to target the company users, and their deception is the same as that of usually attacking Windows.
GAIM and libtiff affected by the attack are used to decode TIFF images by a variety of Linux graphics programs. Just last week, a series of serious viruses have also occurred, and there is also an impact on Linux's libPng, XPDF and CUPS.
Researchers Chase Evans disclosed a range of boundaries, which affect libTIFF RLE decoding parts and produce a large buffer overflow. Malicious hackers can use these vulnerabilities to take deceptive means to attack other users.
Evans said that these vulnerabilities he disclosed may be just a "iceberg", there may be many possibilities that may not be disclosed. Unfortunately, because libTIFF is very large, it is only possible to finish the vulnerability. These vulnerabilities may represent other viruses.
Novell's SUSE Linux and Red Hat Company have put forward recommendations on LibTIFF on weekends and released related patches.
