Severity: Normal Title: UnAce: Buffer overflow and directory traversal vulnerabilities Date: February 28, 2005 Bugs: #81958 ID: 200502-32

Synopsis ========
UnAce is vulnerable to several buffer overflow and directory traversal attacks.
Background ==========
UnAce is an utility to extract, view and test the contents of an ACE archive.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/unace <= 1.2b *>= 1.2b-r1 app-arch/unace >= 2.0 *>= 1.2b-r1
Description ===========
Ulf Harnhammar discovered that UnAce suffers from buffer overflows when testing, unpacking or listing specially crafted ACE archives (CAN-2005-0160). He also found out that UnAce is vulnerable to directory traversal attacks, if an archive contains "./.." sequences or absolute filenames (CAN-2005-0161).
Impact ======
An attacker could exploit the buffer overflows to execute malicious code or the directory traversals to overwrite arbitrary files.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All UnAce users should upgrade to the latest available 1.2 version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/unace-1.2b-r1"
