Two vulnerabilities have been reported in Asterisk, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) An error in the Milliwatt application within the "milliwatt_generate()" function (apps/app_milliwatt.c) when copying internal data samples can be exploited to cause a crash via specially crafted packets.
Successful exploitation of this vulnerability requires that Milliwatt is using the "o" option.
This vulnerability is reported in versions 1.4.x prior to 1.4.44, 1.6.x prior to 220.127.116.11, 1.8.x prior to 18.104.22.168, and 10.x prior to 10.2.1.
2) An error in the "ast_parse_digest()" function (main/utils.c) when handling "HTTP Digest Authentication" information can be exploited to cause a stack-based buffer overflow via an overly long string.
Successful exploitation of this vulnerability may allow execution of arbitrary code.
This vulnerability is reported in versions 1.8.x prior to 22.214.171.124 and 10.x prior to 10.2.1.
