Summary

Off-by-one error in the rfc822_output_char function in the RFC822BUFFER routines in the University of Washington (UW) c-client library, as used by the UW IMAP toolkit before imap-2007e and other applications, allows context-dependent attackers to cause a denial of service (crash) via an e-mail message that triggers a buffer overflow.

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.

    descriptionThe remote host is affected by the vulnerability described in GLSA-201001-03 (PHP: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in PHP. Please review the CVE identifiers referenced below and the associated PHP release notes for details. Impact : A context-dependent attacker could execute arbitrary code via a specially crafted string containing an HTML entity when the mbstring extension is enabled. Furthermore a remote attacker could execute arbitrary code via a specially crafted GD graphics file. A remote attacker could also cause a Denial of Service via a malformed string passed to the json_decode() function, via a specially crafted ZIP file passed to the php_zip_make_relative_path() function, via a malformed JPEG image passed to the exif_read_data() function, or via temporary file exhaustion. It is also possible for an attacker to spoof certificates, bypass various safe_mode and open_basedir restrictions when certain criteria are met, perform Cross-site scripting attacks, more easily perform SQL injection attacks, manipulate settings of other virtual hosts on the same server via a malicious .htaccess entry when running on Apache, disclose memory portions, and write arbitrary files via a specially crafted ZIP archive. Some vulnerabilities with unknown impact and attack vectors have been reported as well. Workaround : There is no known workaround at this time.
