GLSA-200404-11 : Multiple Vulnerabilities in pwlib
Critical Nessus Plugin ID 14476
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200404-11 (Multiple Vulnerabilities in pwlib)
Multiple vulnerabilities have been found in the implementation of protocol H.323 contained in pwlib. Most of the vulnerabilies are in the parsing of ASN.1 elements which would allow an attacker to use a maliciously crafted ASN.1 element to cause unpredictable behavior in pwlib.
An attacker may cause a denial of service condition or cause a buffer overflow that would allow arbitrary code to be executed with root privileges.
Blocking ports 1719 and 1720 may reduce the likelihood of an attack. All users are advised to upgrade to the latest version of the affected package.
SolutionAll pwlib users are advised to upgrade to version 1.5.2-r3 or later:
# emerge sync # emerge -pv '>=dev-libs/pwlib-1.5.2-r3' # emerge '>=dev-libs/pwlib-1.5.2-r3'
