PARTIAL Summary
Buffer overflow in the GetStatistics64 remote procedure call (RPC) in OpenAFS 1.4.8 before 1.6.7 allows remote attackers to cause a denial of service (crash) via a crafted statsVersion argument.
Vulnerable Configurations
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 Scientific Linux Local Security Checks NASL id SL_20140411_OPENAFS_ON_SL5_X.NASL description An attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the server. The GetStatistics64 remote procedure call (RPC) was introduced in OpenAFS 1.4.8 as part of the support for fileserver partitions larger than 2 TiB. The GetStatistics64 RPC is used by remote administrative programs to retrieve statistical information about fileservers. The GetStatistics64 RPC requests do not require authentication. A bug has been discovered in the GetStatistics64 RPC which can trigger a fileserver crash. The version argument of the GetStatistics64 RPC is used to determine how much memory is allocated for the RPC reply. However the range of this argument is not validated, allowing an attacker to cause insufficient memory to be allocated for the statistical information reply buffer. Clients are not affected. last seen 2020-03-18 modified 2014-04-10 plugin id 73454 published 2014-04-10 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/73454 title Scientific Linux Security Update : openafs on SL5.x, SL6.x i386/x86_64 (20140411) NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_C0C31B27BFF311E39D09000C2980A9F3.NASL description The OpenAFS development team reports : An attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the server. The buffer overflow can be triggered by sending an unauthenticated request for file server statistical information.

Integer overflow in ptserver in OpenAFS before 1.6.2 allows remote attackers to cause a denial of service (crash) via a large list from the IdToName RPC, which triggers a heap-based buffer overflow (CVE-2013-1795). OpenAFS before 1.4.15, 1.6.x before 1.6.5, and 1.7.x before 1.7.26 uses weak encryption (DES) for Kerberos keys, which makes it easier for remote attackers to obtain the service key (CVE-2013-4134). The vos command in OpenAFS 1.6.x before 1.6.5, when using the -encrypt option, only enables integrity protection and sends data in cleartext, which allows remote attackers to obtain sensitive information by sniffing the network (CVE-2013-4135). Buffer overflow in the GetStatistics64 remote procedure call (RPC) in OpenAFS 1.4.8 before 1.6.7 allows remote attackers to cause a denial of service (crash) via a crafted statsVersion argument (CVE-2014-0159). A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior (CVE-2014-3660). The updated packages have been upgraded to the 1.4.15 version and patched to correct these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 79989 published 2014-12-15 reporter This script is Copyright (C) 2014-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/79989 title Mandriva Linux Security Advisory : openafs (MDVSA-2014:244) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-2899.NASL description Michael Meffie discovered that in OpenAFS, a distributed filesystem, an attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the fileserver, and potentially permitting the execution of arbitrary code. In addition, this update addresses a minor denial of service issue: the listener thread of the server will hang for about one second when receiving an invalid packet, giving the opportunity to slow down the server to an unusable state by sending such packets. last seen 2020-03-17 modified 2014-04-10 plugin id 73441 published 2014-04-10 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/73441 title Debian DSA-2899-1 : openafs - security update NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_09F47C51C1A611E3A5AC001B21614864.NASL description Debian reports : Heap-based buffer overflow in msadpcm.c in libaudiofile in audiofile 0.2.6 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted WAV file. last seen 2020-06-01 modified 2020-06-02 plugin id 73549 published 2014-04-16 reporter This script is Copyright (C) 2014-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/73549 title FreeBSD : libaudiofile -- heap-based overflow in Microsoft ADPCM compression module (09f47c51-c1a6-11e3-a5ac-001b21614864)
