Mandrake Linux Advisories: squid, ethereal

Mar 31, 2004, 15:51 (0 Talkback[s])

Mandrakelinux Security Update Advisory


Package name: squid
Advisory ID: MDKSA-2004:025
Date: March 30th, 2004
Affected versions: 9.1, 9.2, 10.0, Corporate Server 2.1, Multi Network Firewall 8.2


Problem Description:

A vulnerability was discovered in squid version 2.5.STABLE4 and earlier with the processing of %-encoded characters in a URL. If a squid configuration uses ACLs (Access Control Lists), it is possible for a remote attacker to create URLs that would not be properly tested against squid's ACLs, potentially allowing clients to access URLs that would otherwise be disallowed.

As well, the provided packages for Mandrake Linux 9.2 and 9.1 include a new Access Control type called "urllogin" which can be used to protect vulnerable Microsoft Internet Explorer clients from accessing URLs that contain login information. While this Access Control type is available, it is not used in the default configuration.

The updated packages are patched to protect against these vulnerabilities.

Mandrakelinux Security Update Advisory


Package name: ethereal
Advisory ID: MDKSA-2004:024
Date: March 30th, 2004
Affected versions: 9.1, 9.2


Problem Description:

A number of serious issues have been discovered in versions of Ethereal prior to 0.10.2. Stefan Esser discovered thirteen buffer overflows in the NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP dissectors. Jonathan Heusser discovered that a carefully-crafted RADIUS packet could cause Ethereal to crash. It was also found that a zero-length Presentation protocol selector could make Ethereal crash. Finally, a corrupt color filter file could cause a segmentation fault. It is possible, through the exploitation of some of these vulnerabilities, to cause Ethereal to crash or run arbitrary code by injecting a malicious, malformed packet onto the wire, by convincing someone to read a malformed packet trace file, or by creating a malformed color filter file.

The updated packages bring Ethereal to version 0.10.3 which is not vulnerable to these issues.
