|Gentoo Linux Security Advisory
Title: Asterisk: Multiple vulnerabilities (GLSA 201209-15)
Date: September 26, 2012
Bug(s): #425050, #433750
Multiple vulnerabilities have been found in Asterisk, the worst of
which may allow execution of arbitrary code.
Asterisk is an open source telephony engine and toolkit.
Vulnerable: < 22.214.171.124
Unaffected: >= 126.96.36.199
Architectures: All supported architectures
Multiple vulnerabilities have been found in Asterisk:
- An error in manager.c allows shell access (CVE-2012-2186).
- An error in Asterisk could cause all RTP ports to be exhausted
- A double-free error could occur when two parties attempt to
manipulate the same voicemail account simultaneously (CVE-2012-3863).
- Asterisk does not properly implement certain ACL rules
A remote, authenticated attacker could execute arbitrary code with the
privileges of the process, cause a Denial of Service condition, or bypass
outbound call restrictions.
There is no known workaround at this time.
All Asterisk users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-188.8.131.52"
