Severity: Normal Title: RAR: Format string and buffer overflow vulnerabilities Date: November 13, 2005 Bugs: #111926 ID: 200511-10

Synopsis ========
RAR contains a format string error and a buffer overflow vulnerability that may be used to execute arbitrary code.
Background ==========
RAR is a powerful archive manager that can decompress RAR, ZIP and other files, and can create new archives in RAR and ZIP file format.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/rar < 3.5.1 >= 3.5.1
Description ===========
Tan Chew Keong reported about two vulnerabilities found in RAR:
* A format string error exists when displaying a diagnostic error message that informs the user of an invalid filename in an UUE/XXE encoded file.
* Some boundary errors in the processing of malicious ACE archives can be exploited to cause a buffer overflow.
Impact ======
A remote attacker could exploit these vulnerabilities by enticing a user to:
* decode a specially crafted UUE/XXE file, or
* extract a malicious ACE archive containing a file with an overly long filename.
When the user performs these actions, the arbitrary code of the attacker's choice will be executed.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All RAR users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/rar-3.5.1"
