Detail
Problem Description: An updated elinks package that fixes two security issues is now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: ELinks is a text-based Web browser. ELinks does not display any images, but it does support frames, tables, and most other HTML tags. An off-by-one buffer overflow flaw was discovered in the way ELinks handled its internal cache of string representations for HTML special entities. A remote attacker could use this flaw to create a specially-crafted HTML file that would cause ELinks to crash or, possibly, execute arbitrary code when rendered. (CVE-2008-7224) It was discovered that ELinks tried to load translation files using relative paths. A local attacker able to trick a victim into running ELinks in a folder containing specially-crafted translation files could use this flaw to confuse the victim via incorrect translations, or cause ELinks to crash and possibly execute arbitrary code via embedded formatting sequences in translated messages. (CVE-2007-2027) All ELinks users are advised to upgrade to this updated package, which contains backported patches to resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 235411 - CVE-2007-2027 elinks tries to load .po files from a non-absolute path 523258 - CVE-2008-7224 elinks: entity_cache static array buffer overflow (off-by-one) |

Description: | Teemu Salmela discovered that Elinks did not properly validate input when processing smb:// URLs. If a user were tricked into viewing a malicious website and had smbclient installed, a remote attacker could execute arbitrary code with the privileges of the user invoking the program. Jakub Wilk discovered a logic error in Elinks, leading to a buffer overflow. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program | ||

Description: | Jakub Wilk discovered an off-by-one buffer overflow in the charset handling of elinks, a feature-rich text-mode WWW browser, which might lead to the execution of arbitrary code if the user is tricked into opening a malformed HTML page. For the old stable distribution, this problem has been fixed in version 0.11.1-1.2etch2. The stable distribution and the unstable distribution already contain a patch for this problem. We recommend that you upgrade your elinks package. | ||
