Vulnerabilities > CVE-2006-2923 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Loudhush 1.3.6
Summary
The iax_net_read function in the iaxclient open source library, as used in multiple products including (a) LoudHush 1.3.6, (b) IDE FISK 1.35 and earlier, (c) Kiax 0.8.5 and earlier, (d) DIAX, (e) Ziaxphone, (f) IAX Phone, (g) X-lite, (h) MediaX, (i) Extreme Networks ePhone, and (j) iaxComm before 1.2.0, allows remote attackers to execute arbitrary code via crafted IAX 2 (IAX2) packets with truncated (1) full frames or (2) mini-frames, which are detected in a length check but still processed, leading to buffer overflows related to negative length values.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-200606-30.NASL description The remote host is affected by the vulnerability described in GLSA-200606-30 (Kiax: Arbitrary code execution) The iax_net_read function in the iaxclient library fails to properly handle IAX2 packets with truncated full frames or mini-frames. These frames are detected in a length check but processed anyway, leading to buffer overflows. Impact : By sending a specially crafted IAX2 packet, an attacker could execute arbitrary code with the permissions of the user running Kiax.
