Description:
A vulnerability has been reported in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an input validation error in the SNMP module within the "asn_parse_header()" function when handling certain negative length fields. This can be exploited to restart Squid by sending a UDP datagram containing specially crafted header length combinations.
Successful exploitation requires that SNMP support is enabled.
The vulnerability affects 2.x versions prior to 2.5.STABLE7 and 3.x versions prior to 3.0.STABLE7.
