Summary

Heap-based buffer overflow in the pefromupx function in libclamav/upx.c in Clam AntiVirus (ClamAV) 0.81 through 0.88.3 allows remote attackers to execute arbitrary code via a crafted UPX packed file containing sections with large rsize values. This vulnerability is addressed in the following product release: Clam Anti-Virus, ClamAV, 0.88.4

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.

    descriptionDamian Put discovered a boundary error in the UPX extraction module in ClamAV which is used to unpack PE Windows executables. This could be abused to cause a Denial of Service issue and potentially allow for the execution of arbitrary code with the permissions of the user running clamscan or clamd. Updated packages have been patched to correct this issue.

    (ClamAV: Heap buffer overflow)
    
        Damian Put has discovered a boundary error in the pefromupx() function
        used by the UPX extraction module, which unpacks PE Windows executable
        files. Both the 'clamscan' command-line utility and the 'clamd' daemon
        are affected.
      
    Impact :
    
        By sending a malicious attachment to a mail server running ClamAV, a
        remote attacker can cause a Denial of Service and potentially the
        execution of arbitrary code with the permissions of the user running
        ClamAV.
      
    Workaround :
    
        There is no known workaround at this time."
