[GLSA-200511-10] RAR: Format string and buffer overflow vulnerabilities

Vulnerability Assessment Summary
RAR: Format string and buffer overflow vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200511-10
(RAR: Format string and buffer overflow vulnerabilities)

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.
