    ========
    
    LHa has a buffer overflow in its compression utility with unspecified
    impact.
    
    Background

    LHa is a console-based program for packing and unpacking LHarc
    archives.

      1  app-arch/lha             < 114i_p20201004      >= 114i_p20201004
    
    Description
    ===========
    
    A buffer overflow in LHa's compression code was discovered which can be
    triggered by a crafted input file.
    
    Impact

    There is no known workaround at this time.
    
    Resolution
    ==========
